The Role of Transformational and Transactional Leadership Approaches on Environmental and Ethical Aspects of CSR

Corporations’ accountabilities to implement socially responsible actions towards stakeholders are essential as organizations keep participating in competitive industries. Recently, applying leadership approaches has been the emphasis of both scholars and practitioners, but the concern has not been comprehensively examined. The purpose of this study is to investigate the influence of transformational and transactional leadership styles on environmental and ethical features of Corporate Social Responsibility (CSR), in financial services companies located in the United Kingdom (UK). The moderating factor of employees’ years of employment in their respective companies is also examined. Offering contributions through an empirical appraisal of leadership and CSR is aimed. 384 employees working in the financial services companies in the UK were given a structured questionnaire to test our model. The employees offered viewpoints on the leaders, their selves, and the company. Suggested hypotheses were tested through Structured Equation Modelling (SEM). The study concluded that both transformational and transactional leadership approaches had positive impacts on the environmental and ethical aspects of CSR. Additionally, the moderating variable only had an impact on the relationship between transformational leadership and ethical CSR. The study proposes that complementary implementation of transformational and transactional leadership approaches can lead to enhanced socially responsible actions in organizations.


Introduction
In recent decades, Corporate Social Responsibility (CSR) has received the noteworthy attention of both academics and practitioners in business fields, especially on the features of environmental and ethical CSR [1,2]. Clarifying CSR is not a straightforward task; accordingly, it can be contingent upon perspective and point of view [3]. It can theoretically intersect with several other ideas, such as citizenship, sustainability, and ethics. CSR nurtures the prominence of meaning in work and life to equal status as well as ecological integrity and financial sustainability. It likewise helps to recognize what essentially companies are doing with their profits and how they are affecting society. The mounting emphasis on CSR is not to focus on shareholder standpoint by maximization of profit, but to highlight the stakeholders' perspective, including customers, government, suppliers, employees, and their prosperity [4]. In the sense of this exploration, the focus is on the employees' standpoint with regard to the environmental and ethical aspects of the business.
However, there is huge pressure for shareholder returns on the leaders of corporations, which can cause them to adopt a singular approach towards profit generation [5]. In addition, with the challenge of escalating globalization and intensifying competition leading to ethical conflicts, managerial leaders are challenged with the responsibility of setting ethical standards that oversee the behaviors of their employees within their organizations [6]. Huge business scandals of corporations such as Tyco international, Worldcon, Within the context of this research, the financial services sector in the UK is deliberated to be central to explore the CSR concept, since this sector has been faced with complications such as low disclosure levels of CSR reports of businesses operating in the financial services sector of the UK, as well as negative social impact due to periodically massive restructuring and redundancies in employment, where the UK based workforces of banks like Citigroup and Royal Bank of Scotland were made redundant [24]. However, Day and Woodward [25] highlighted that such low disclosure is related to size, as the likelihood of compliance rises with bigger companies, which might indicate a resource issue. On the contrary, there are substantial actions towards CSR as well, with the application of the green finance concept, where the funding of investors is directed towards making improvement on acknowledged environmental goals, as 26 investment companies and unit trusts play an active role in this process, including giant corporations such as Parvest and Allianz [26].
Inclusion of the leadership styles is believed to be imperative to this research, after perceiving such increasing action towards CSR in the financial services industry. However, the previous research in the UK financial services sector has linked leadership styles with organizational performance and organizational culture [27], or used differing leadership styles with regard to CSR, such as visionary and servant leadership [28]. Consequently, in the financial services sector of UK, there is a lack of research carried out to examine the effect of transactional and transformational leadership styles on environmental and ethical CSR, with the moderating effect of employees' years of employment in their respective company. In consequence, this research intends to fill the gap. This research can present outcomes that will potentially present clear pathways to the leaders of the financial services companies to consider specific styles of leadership that can result in socially responsible actions, which benefits the whole society. Moreover, the findings can be the starting point of more profound research in the area of leadership and CSR in the financial services sector.
The remaining parts of this article are prepared in the following manner. The subsequent section provides the literature review, which leads to hypotheses development. After Section 2, Section 3 delivers the clarification of the methodology in detail, which includes the data collection method and procedure, sample, as well as the method of data analysis. Section 4 explains the data with its analysis and findings, and then the study is settled with discussion and conclusion presented in Section 5. CSR-related research has been previously applied to public relations, business ethics, corporate sustainability, and leadership. One of the ways to define CSR is a company's commitment to managing the environmental, economic, and social influences of its actions sensibly and in line with public expectations [29]. However, CSR is a very broad concept that can take various forms according to the company and its operating industry [30]. For instance, certain businesses adopt philanthropic actions through donating money or services, as well as in the form of non-profit organizations. On the other hand, others could focus on the environmental aspect of CSR by engaging in the production of environmentally friendly goods. However, the approaches are similar in the sense that they aim to manage their processes with the aim of impacting society positively.

Literature Review and Hypotheses
The concept of social responsibility was noticeable even centuries ago. Nevertheless, the first work of the literature with regard to businesses socially responsible practices, as well as addressing what those responsibilities are, was noticed in the 1950s, where Bowen [31] clarified CSR as "the obligations of business to pursue those policies, to make those decisions or to follow those lines of action which are desirable in terms of the objectives and values of our society". CSR started to be widely used in the 1970s. Globalization was one of the crucial elements in the extensive use of CSR since the development of many multinational companies increased the need for transparency as well as social responsibility [32]. Moreover, two publications made by the Committee for Economic Development (CED) during the 1970s acknowledged that businesses' basic purpose is to constructively serve the needs of the society, which established the social expectations of the public with regard to CSR [33]. In the 1980s, Jones [34] proposed the interesting perspective of CSR under two facets. The first one was the voluntary actions unaffected by the compulsory forces of law, whereas the second facet was a broad obligation that goes beyond the stakeholders.
Moving on to the 1990s, certain themes of CSR continued developing such as corporate citizenship, stakeholder theory, business ethics, and sustainability. Global events like the creation of the European Environment Agency (1990) and the implementation of the Kyoto Protocol (1997) had major roles in the development of CSR in this era. During the 21st century, the CSR concept was evolved further with the addition of new terminologies as well as establishing firm connections with other concepts. One of the keystones was Smith's [35] explanation that companies need to implement CSR into their strategic perspectives with the aim of fulfilling their long-term obligations towards society. Subsequently, this approach was popularly used as strategic CSR in different contexts. Moreover, a different perspective on CSR was the new strategic business that includes the commitment of corporations with the backing of the systematic allocation of resources for conveying respect and promotion to individual rights, society growth, and environmental care [36]. Due to the massive global impact of the Covid-19 pandemic in current times, CSR practices of businesses are likewise challenged in the UK. However, He and Harris [37] debate whether corporations can assess the current situation as an opportunity to address urgent environmental matters through adopting more genuine and reliable CSR practices. As an example, the European Union (EU) has demonstrated observable levels of adaptability during such crises, through increasing its attention on climate change [38].
Ethical CSR is a more broad-spectrum in the sense that ethics are a fundamental part of all the previously mentioned aspects of CSR, but environmental corporate social responsibility (ECSR) has become a distinctively crucial topic in recent times, after the substantial increase in environmental issues occurring as a result of businesses inconsiderate actions. ECSR can be defined as a concept on companies' extra effort of incorporating environmental concerns in their business operations and their interaction with their stakeholders [39]. It is viewed as the contribution that firms make to sustainable development by balancing and improving environmental impacts without damaging economic performance. At an international level, the International Chamber of Commerce has sanctioned a Business Charter for Sustainable Development which contains numerous principles that should be obliged by private companies with the aim of achieving sustainable growth. Flammer [40] concluded that ECSR improves stakeholders' relationships and reactions with each other as well as attracting a higher number of customers. Other CSR actions also have led to rewarding contributions towards the environment, including forest conservation, water cleansing drives, afforestation, and environmental awareness [41]. Research has likewise discovered that corporations that are eco-friendly and demonstrate good CSR practices enjoy increased consumer purchase preference [42].
In addition, the study of Abdul and Ibrahim [43] conducted in Malaysia suggests that whether an organization is displaying CSR actions can depend on the characteristics and style of the leaders in the company. Agle et al. [44] have similarly found strong support on the relationship between the values of CEO's and corporate social performance, which highlights the importance of leadership on CSR.

Leadership
Leadership is a major subject that is widely researched and discussed, where research dates back to Galton's study of Hereditary Genius [45], advocating that leaders' qualities are genetic and transported from generation to generation. Batten [46] defined leadership as "the development of a clear and complete system of expectations in order to identify evoke and use the strengths of all resources in the organization the most important of which is people". Northouse [47] enlisted numerous components central to the phenomenon of leadership such as: leadership being a process, leadership containing influencing others, Sustainability 2021, 13, 1411 5 of 23 and goals being shared by leaders and their followers. The differences in definitions of leadership by scholars are present in how leaders motivate, and who has a say in the aims of the organization [48]. In recent times, the main focus of the leaders is shifting from "forcing" followers to "persuasion", then "influencing", and lastly followed by leaders and followers influencing each other. Hofstede [49] deliberated the relationships among leadership, subordination, and culture, where the finding was presented that leadership and subordination are inseparable, and ideas about leadership reflect the dominant culture of a country. Bennis and Nanus [50], after exploring the subject for a considerable amount of time, stated that "never have so many labored so long to say so little" and "leadership is the most studied and least understood topic of any in the social sciences".
It is viewed as essential to examine the history of leadership theories to appreciate how transactional and transformational theories emerged. At the outset, trait theories tended to focus on personality, physical, social, or intellectual traits in order to distinguish leaders from non-leaders [51]. Some examples of leadership traits are extroversion, openness, and conscientiousness [52]. Findings of a meta-analysis showed that the Big Five personality dimensions were substantial predictors of leader effectiveness and leadership emergence, which supports certain claims of trait theories of leadership [53]. Myung and Choi [54] demonstrated that leaders' "dark triad" trait, which is a psychological term explaining negative dispositions, undesirably affects the perception of CSR. On the other hand, trait theories were criticized for the suggestion that traits do not change in different situations so people are the same at all times.
Looking beyond the trait paradigm, studies on leadership focused on how behaviors predicted leader effectiveness inside the organizations, inclusive of the CSR aspect. Behavioral theories of leadership suggest that specific behaviors differentiate leaders from non-leaders, so identifying and teaching them to potential leaders is possible. The biggest difference in behavioral theories compared with trait theories is the suggestion that leadership is not predetermined and can be taught. Behavioral theories narrowed the explanation of leader behavior to two dimensions: initiating structure and consideration [55]. Blake and Mouton's [56] Managerial Grid theory focused on different types of behaviors to assess leadership styles, such as concern for people, and concern for production. Moreover, Mcgregor [57] conveyed Theory X and Theory Y, proposing two aspects of human behavior at work. The theory promoted participative decision-making and team development by assisting individual requirements and aligning individual and group purposes. However, it was challenging to state which style of leadership was important in enabling one group to function better than the other. Therefore, it is almost impossible to determine one leadership style which would be accurate for all leaders under all circumstances.
Accordingly, the next phase of leadership theories focused on contingency theories, which dealt with the missing link of the environment in which the leader exists. Contingency theories do not completely disregard the leaders' personality and behavior but did not consider them as the most important dynamics for defining the success of the leader. According to Fiedler's [58] contingency model, a leader is effective when his or her style of leadership fits with the requirements of the situation. Moreover, the path-goal theory of House and Mitchell [59] was a process in which leaders chose particular behaviors that are best fitted to the employees' requirements and the working environment, so that they may best guide the workers through their path in the obtainment of their daily work activities. However, one criticism aroused when assessing Fiedler's model, which was contingency variables being complex and difficult to determine [60].
Moving onto the contemporary approaches of leadership, it can be seen that they are primarily focused on the personal influence of the leader to develop and inspire followers in order to achieve organizational goals and make a difference in the community. Some examples include charismatic leadership, transactional leadership, transformational leadership, and servant leadership. House [61] argued that charismatic leadership is rooted in behavioral and personal characteristics of the leaders, and such qualities can inspire followers through the appropriate articulation of the organizational vision. Besides that, servant leadership comprises the leader displaying the features of empathy, listening, stewardship, and commitment to personal growth toward others [62].
As contemporary approaches which stand out, transformational and transactional leadership theories were initially introduced to the literature as a concept by Burns [63]. Subsequently, Bass [64] developed the theory and stated that transactional and transformational leadership are independent but complementary ideas. The style of transactional leadership is where leaders motivate followers in the direction of established goals through a reward and punishment system [65]. In exchange for receiving the required work satisfactorily within the agreed time limits, the leader awards the followers with rewards for their performance. Major components of transactional leadership are the contingent reward, management by exception, and laissez-faire [66]. To begin with, the contingent reward component is related to the contribution of rewards in terms of extra pay or bonuses. Such leadership behavior is concentrated on describing effort-reward relationships and contains interactions that take place between a leader and the followers. Management by exception can occur either passively, where the leader intervenes only when the standards are not met, or actively when the leader is involved during the whole process taking corrective actions. Even though a corrective approach may be observed as negative, an active approach tends to be effective in certain circumstances. Lastly, laissez-faire leaders give the employees complete autonomy, and they completely avoid getting involved regarding how they do their work [67].
Transformational leadership can be defined as inspiring employees to transcend their self-interests for the benefit of the organization, which can also have an extraordinary effect on followers. These leaders create an appearance of convincing and encouraging vision for the future [68]. On the other hand, Yukl [69] stated that similar to most leadership theories, transformational leadership theory adopts a heroic leadership stereotype, where effective performance by an organization, group, or individual is assumed to be contingent solely on leadership by an individual with the abilities to find the accurate path and motivate others to take it. Four chief features are idealized: influence, inspirational motivation, intellectual stimulation, and individualized consideration. Idealized influence is concerned with providing vision and a sense of purpose, which creates admiration, belief, and confidence from followers [70]. Inspirational motivation is about being able to encourage followers to have the same passion and motivation to fulfill organizational goals. The inspirational motivation and idealized influence dimensions are vastly correlated and are occasionally combined to form a measure of charisma [71]. Displaying the intellectual stimulation character instigates employees to discover new ways of doing things, as well as generating new opportunities to learn. Last of all, individualized consideration is regarded as giving personal attention to followers, and making individuals feel exclusively valued.

Hypotheses Development
Previous research on leadership largely agreed that although there are many aspects to leadership, they commonly have important effects on corporate social responsibility. Some of these leadership attributes are authenticity [72], morality [73], as well as rolemodelling [74]. Furthermore, particular leadership approaches such as ethical leadership have both direct and indirect effects on CSR, through encouraging adhocracy values in organizations [75]. According to Waldman et al. [7], research that ignores the role of leadership in CSR may perhaps yield imprecise deductions with regard to the antecedents and consequences of CSR activities. Eventually, implementing efficient leadership strategies has crucial effects on the CSR actions of employees as well as the operating system of corporations. Centered on the above argument, the hypotheses for this article were generated.
Referring to Juneja [76], transactional leaders are established to be moderately effective in managing efficiency decisions that are intended at improving productivity and lowering costs. Moreover, they are highly instruction and action-oriented, and their association with the followers tends to be transitory as well as not being based on emotional bonds. According to Jacobs et al. [77], transactional and transformational leadership styles can Sustainability 2021, 13, 1411 7 of 23 work in conjunction with each other and express value to each other through interaction. Both types of leadership styles might be required in the same business in order to equalize each other and assist to achieve the growth and development of objectives. Transactional leaders ensure the team is running smoothly and producing results in the present day, whereas transformational leaders put emphasis on innovation and seek future advances.
Preceding research provided unsettled outcomes, especially with regard to the relationship of transactional leaders with different aspects of CSR. For instance, even though Kanungo [78] led a research on the ethical values of leaders, and concluded that transactional leadership behavior is ethical based on certain sets of values that are teleological with mutual philanthropic motives; the same study exhibited that other leadership styles like charismatic leadership are rooted in stronger ethical values. In addition, the statements were proposed that there is a relationship between transactional leadership and CSR practices, although it is not as strong as transformational leadership with regard to ethical and environmental aspects, respectively [79,80]. Furthermore, Tuan [81] has found that transactional leaders are prone to CSR activities merely when the organizations' primary stakeholder is emphasized, which includes only certain aspects of CSR such as legal and economic. Eventually, the correct application of transactional leadership with proper incentives can potentially lead to higher successful CSR practices [82]. In line with the argument above, the following two hypotheses were proposed: Hypothesis 1 (H1). Transactional Leadership will positively influence Ethical CSR.

Hypothesis 2 (H2). Transactional Leadership will positively influence Environmental CSR.
The theory of transformational leadership differentiates itself from the preceding contemporary theories, based on its alliance to a greater good, since it involves the participation of the followers in activities that will lead to a certain superior social dividend. Leaders displaying transformational actions receive high respect, trust, and loyalty from their subordinates and, in return, they make an additional effort to ensure that leaders understand their employees' requests and feelings [83]. Bass and Avolio [84] state that the style of transformational leadership crosses hierarchical echelons so it is transparent on the bottom floor as well as at the top of the hierarchical chain. Waldman et al. [85], advocates that CEOs displaying transactional leadership characteristics significantly improve the performance of their organizations. Transformational leaders are also identified as exhibiting more citizenship behaviors such as sportsmanship, altruism, and courtesy, as well as aiming to instill the same values in their subordinates [86]. The full range of leadership, as measured by the Multifactor Leadership Questionnaire (MLQ), indicates that all leaders display a frequency of both the transformational and transactional features, but each leader's profile includes more of one and less of the other. The leaders who are more satisfying to their subordinates and who are more influential as leaders tend to be more transformational and less transactional.
The findings of transformational leadership dominate the literature with more consistent results. Referring to the study undertaken by Robertson and Barling [17], environmentallyspecific transformational leadership has an important role in the greening of organizations, through positively influencing employees' pro-environmental passion and behaviors. Turner et al. [87], with regard to the ethical aspects, concluded that transformational leaders were perceived by their subordinates with having higher moral reasoning. Moreover, transformational leaders likewise motivate managers into a better understanding and commitment to CSR activities [88]. This study combined theoretical and empirical research and interviewed managers of six different organizations in Australia, and it recommended testing similar approaches in different industries and countries. Besides that, Hadi and Rasool [89] revealed that transformational leadership increases the autonomous motivation of employees, which acts as a catalyst for pro-environmental behaviors at their respective workplaces. Moreover, perceived CSR is found to mediate the relationship between transformational leadership and affective organizational commitment, as well as trans- formational leaders increasing social responsibility through the perception of staff [90]. Even though this research will look for direct links between transformational leadership and environmental and ethical CSR, grounded on prior arguments, the subsequent two hypotheses were suggested: Hypothesis 3 (H3). Transformational Leadership will positively influence Ethical CSR.

Hypothesis 4 (H4). Transformational Leadership will positively influence Environmental CSR.
Stakeholder theory suggests that the demographic composition of leaders leads to different strategic choices, including the area of CSR [91]. As an example, Spanish women were established to be more adaptable and effective in comparison to Spanish men while implementing CSR practices, through applying the transformational leadership approach [92]. Tenure, which can be referred to as years of employment in the current company, is likewise part of this demographic composition. Employees' length of time at their respective companies increases their association with leaders, thus, they become more influenced from their leaders.. With amassing tenure in organizations, employees tend to become progressively acquainted with their role as well as the corporate norms, objectives, and organizational culture [93]. Huang [94] observed 392 firms from a sample of 661 to explore the relationship between CEO characteristics and consistency in CSR, declaring that CEO length of employment positively affects CSR performance. The study of Steffens et al. [95], on organizational tenure in the financial industry, found that employee tenure is positively correlated with organizational performance, in association with other factors such as team and leader tenure. The common observation from such studies is the occurrence of years of employment in the company affect employee behavior, organizational commitment, and taking charge [96][97][98], which can potentially create the circumstance of moderating the relationship between leadership styles and CSR. Because of these arguments, the following hypotheses were proposed: Hypothesis 5 (H5). Employees' years of employment in the current company will positively moderate the relationship between Transformational Leadership and Environmental CSR.
Hypothesis 6 (H6). Employees' years of employment in the current company will positively moderate the relationship between Transformational Leadership and Ethical CSR.

Hypothesis 7 (H7).
Employees' years of employment in the current company will positively moderate the relationship between Transactional Leadership and Environmental CSR.

Hypothesis 8 (H8).
Employees' years of employment in the current company will positively moderate the relationship between Transactional Leadership and Ethical CSR.

Methodology
The financial services sector is becoming more apprehensive with CSR, due to an increasing concern towards CSR throughout the whole world, which inspires leaders to make wiser decisions on this aspect. Because of that, the introduction of concepts such as "green finance" are gaining extensive attention from investors. Leaders can create desirable CSR actions in the corporations by influencing their subordinates. When the employees individually feel that CSR is an important factor of their work, the process of changing the organizational actions would be simplified towards ethical and environmentally responsible actions. It is critical for financial services firms to avoid adopting a singular approach towards profit generation. In light of these considerations, the objective of this study is to examine the effects of leadership styles on Corporate Social Responsibility, with the moderating effect of years of employment of employees, on financial services companies located in the UK. Precisely, the goal is to investigate the effects of transformational leadership and transactional leadership on environmental CSR and ethical CSR. In the current research, the model presented in the following Figure 1 demonstrates the links between leadership approaches, CSR aspects and the moderating variable. ees individually feel that CSR is an important factor of their work, the process of changing the organizational actions would be simplified towards ethical and environmentally responsible actions.

Methods of Data Collection and Analysis
Measuring the "Transformational Leadership" (TF), "Transactional Leadership" (TSC), "Environmental Corporate Social Responsibility" (ECSR), and "Ethical Corporate Social Responsibility" (Ethical CSR) items were shaped through preceding studies [17,99,100]. For the items of transformational and transactional leadership, as have others [17,101,102], we used selected items from the Multifactor Leadership Questionnaire [99] in an attempt to escalate the quantity of responses by keeping the survey precise. TF, TSC, ECSR, and Ethical CSR were measured with 10, 6, 7, and 5 items, respectively, as well as 1 item to determine the moderating variable of employees' years of employment in their current company, out of which 1 item from the TSC measure was established to have a loading value below the threshold and was consequently deleted from rest of the examination (see Appendix A). Participators were asked to provide their perspectives regarding numerous assertions in relation to the independent and dependent variables of the research, to be precise: "Transformational Leadership", "Transactional Leadership", "Environmental Corporate Social Responsibility", and "Ethical Corporate Social

Participators were asked to provide their perspectives regarding numerous assertions in relation to the independent and dependent variables of the research, to be precise: "Transformational Leadership", "Transactional Leadership", "Environmental Corporate Social Responsibility", and "Ethical Corporate Social Responsibility". Measurement of the statements was grounded on a 5-point Likert scale extending from 1 (strongly disagree) to 5 (strongly agree).
Personnel who were employed in financial services organizations in the UK were the targeted population of this research. The list of financial services companies in the UK was taken from Aurigin [103], which is a global deal origination platform that contains such lists for investment opportunities and other purposes. The companies from the financial services industry were selected randomly due to time and resource constraints. Official data from the UK Parliament [22] shows that there are 1.1 million employees working in financial services, who were chosen by way of opportunity sampling. Consequently, the "Survey System" sample size calculator was the technique of outlining the absolute sample size, making an allowance for a 5% margin of error, as well as a 95% confidence level. The size of the sample was measured as 384. One representative employee was contacted from each firm, and they were requested to allocate the questionnaire to the co-workers, to quicken the distribution process. The employees did not have any managerial roles within their respective companies. Necessary background information regarding the research was presented at the outset of all questionnaire forms. The targeted sample size of 384 was reached on the 413th questionnaire directed to the employees. Regarding the demographic characteristics of the sample, the data showed that 225 participants were male (58.9%), and 157 participants were female (41.1%). Moreover, the age distribution of participants is perceived to be largely between 25 and 34 years old (50.3%). The remaining percentage is shared between 18 and 24 years old (27.7%), 35 and 44 years old (13.9%), 45 and 54 years old (5.8%), and above 55 years old (2.4%). The educational background of the sample size is mainly with an undergraduate degree (65.2%), where the others had a postgraduate degree (22%), high school diploma (9.9%), and Ph.D. (2.9%). Additionally, the descriptive statistics and correlations between the main variables are presented in Table 1.

Data Results and Analysis
The data were analyzed by using the Statistical Package for Social Sciences (SPSS) for Windows 25.0 and Analysis of Moment Structures (AMOS) 23.0 programs. Reliability assessment was conducted in order to test the dependability of the questionnaire, as well as applying Confirmatory Factor Analysis through AMOS to test the validity. After that, Structural Equation Modelling (SEM) was applied to perceive the accountability of the hypotheses. SEM was perceived to be an ideal approach for further analysis, as it enables testing of a set of hypotheses simultaneously while accounting for measurement error [104,105].
In addition, it was also tested whether the data were normally distributed, which can be investigated through a Quantile-Quantile Plot drawing [106]. The normal distribution of the data is dependent upon the skewness and kurtosis values being around ±3 [107]. The outlier values increase the error variance of values and, thus, they affect the power of statistical tests. It was checked whether there were outlier values in the data set for such a reason. Since the applied questionnaire was found to be normally distributed, parametric tests were chosen to be applied for statistical assessments. A T-Test was used to compare two independent groups of quantitative data, and Analysis of Variance (ANOVA) was applied to test more than two groups.
The correlation analysis shown in Table 1 was used in order to test the relationship between the variables. As a result, it was comprehended that Transformational Leadership positively correlates with Transactional Leadership (r = 0.764, p < 0.05), Environmental CSR (r = 0.187, p < 0.05), and Ethical CSR (r = 0.552, p < 0.05). Likewise, Transactional Leadership positively correlated with Environmental CSR (r = 0.134, p < 0.05) and Ethical CSR (r = 0.549, p < 0.05). There was a positively correlated relationship between Environmental CSR and Ethical CSR as well (r = 0.253, p < 0.05).
Besides, the following Figure 2 presents the relationship between the independent variables and the dependent variables, which will be analyzed in detail on the subsequent parts of this section. mental CSR and Ethical CSR as well (r = 0.253, p < 0.05).
Besides, the following Figure 2 presents the relationship between the independent variables and the dependent variables, which will be analyzed in detail on the subsequent parts of this section.  The measurement model's reliability was established by utilizing Cronbach's Alpha. The values at the level of 0.60 and above regarding Cronbach Alpha indicate that the measurement is reliable and has high convergent validity [108]. The Cronbach's Alpha calculations showed 0.836 for Transformational Leadership, 0.738 for Transactional Leadership, 0.679 for Environmental CSR, and 0.761 for Ethical CSR, which are all reliable outcomes. In addition, entire correlations between the variables exhibited item factor weights above 0.40, which indicates valid relationships between the variables. These results can be observed in detail from the following Table 2.
Moving to the next measure, the Confirmatory Factor Analysis shows that the Structural Equation Modelling results of the model are meaningful at the level of p = 0.000. The analysis led to the exclusion of one item (TSC5) from the measurement due to the low factor level. The remaining factors were found to be correlated with the model. While improving the model, the variables that lower the fit were determined, and new covariance was formed for high covariance values on residual values. The newly formed index calculations are shown in the following Table 3 where the optimal value levels are reached. The following part of this section will examine the relationship between the variables in detail. To begin with, the relationship between the independent variable of Transformational Leadership and the dependent variable of Environmental CSR was studied, with the addition of employees' years of employment in their current company, which was the moderating variable. The appraisals revealed that Transformational Leadership has a positive and statistically meaningful effect on Environmental CSR (p < 0.05), where 1 unit of increase in Transformational Leadership leads to 0.255 units of increase in Environmental CSR (β = 0.255). This relationship is an acceptable level of fit between the variables. On the other hand, the results showed that the moderating variable of years of employment has no moderating effect on the relationship between Transformational Leadership and Environmental CSR (p > 0.05). These results are shown in the following Figure 3 and Table 4.   The next measurement investigated the relationship between the independent variable of Transactional Leadership and the dependent variable of Environmental CSR, where the moderating variable of years of employment was unchanged. As a result, Transactional Leadership has a positive and statistically meaningful (p < 0.05) effect on Environmental CSR, where 1 unit of increase leads to a-0.187 increase, respectively (β = 0.187), which is an acceptable measure of the fit level. Employees' years of employment in their current companies did not have a significant moderating effect on the relationship between Transactional Leadership and Environmental CSR as well (p > 0.05). These measurements are shown in the following Figure 4 and Table 5.  The next measurement investigated the relationship between the independent variable of Transactional Leadership and the dependent variable of Environmental CSR, where the moderating variable of years of employment was unchanged. As a result, Transactional Leadership has a positive and statistically meaningful (p < 0.05) effect on Environmental CSR, where 1 unit of increase leads to a-0.187 increase, respectively (β = 0.187), which is an acceptable measure of the fit level. Employees' years of employment in their current companies did not have a significant moderating effect on the relationship between Transactional Leadership and Environmental CSR as well (p > 0.05). These measurements are shown in the following Figure 4 and Table 5.   The next feature is on the relationship between the independent variable of Transformational Leadership and the dependent variable of Ethical CSR, where the moderator is stable. Calculations displayed a positive and statistically meaningful (p < 0.05) relationship between the variables, where 1 unit of increase in Transformational Leadership leads to a 0.688-unit increase in Ethical CSR (β = 0.688), which is a satisfactory degree. In addition, years of employment in current the company were measured to have a moderating effect on the relationship between Transformational Leadership and Ethical CSR (p < 0.05). The results are presented fully in the following Figure 5 and Table 6.  The next feature is on the relationship between the independent variable of Transformational Leadership and the dependent variable of Ethical CSR, where the moderator is stable.

In addition, years of employment in current the company were measured to have a moderating effect on the relationship between Transformational Leadership and Ethical CSR (p < 0.05). The results are presented fully in the following Figure 5 and Table 6. After that, the relationship between the independent variable of Transactional Leadership and the dependent variable of Ethical CSR was investigated, with an unchanged moderating variable of years of employment. There was a noteworthy positive relationship (p < 0.05) between the variables, where 1 unit of increase in Transactional Leadership led to a 0.745-unit increase in Ethical CSR (β = 0.745). On the other hand, the moderating variable was not established to have a moderating effect on the relationship between the variables (p > 0.05). The results are shown in the following Figure 6 and Table 7.  After that, the relationship between the independent variable of Transactional Leadership and the dependent variable of Ethical CSR was investigated, with an unchanged moderating variable of years of employment. There was a noteworthy positive relationship (p < 0.05) between the variables, where 1 unit of increase in Transactional Leadership led to a 0.745-unit increase in Ethical CSR (β = 0.745). On the other hand, the moderating variable was not established to have a moderating effect on the relationship between the variables (p > 0.05). The results are shown in the following Figure 6 and Table 7.

Discussion
Contemporary leadership approaches, in terms of their uniqueness and importance, have been increasingly studied by both academics and practitioners. Since there are various approaches to leadership, contemporary theories attempted to emphasize moral discourse and social purpose, which differs from the previous theories mainly focusing on favored management, authority, and production [109]. Prior research on specific contemporary theories of transformational and transactional leadership has generally been on the implementation of the theory and its relationship with job performance [110][111][112]. This study is deliberated as a significant contributor to the present literature since it provides a perspective on the effects of specific contemporary theories on particular aspects of Corporate Social Responsibility, in a scarce area of empirical research.

Discussion
Contemporary leadership approaches, in terms of their uniqueness and importance, have been increasingly studied by both academics and practitioners. Since there are various approaches to leadership, contemporary theories attempted to emphasize moral discourse and social purpose, which differs from the previous theories mainly focusing on favored management, authority, and production [109]. Prior research on specific contemporary theories of transformational and transactional leadership has generally been on the implementation of the theory and its relationship with job performance [110][111][112]. This study is deliberated as a significant contributor to the present literature since it provides a perspective on the effects of specific contemporary theories on particular aspects of Corporate Social Responsibility, in a scarce area of empirical research.
This study was conducted to research the effect of transformational and transactional leadership theories on environmental and ethical aspects of CSR, with the moderating variable of employees' years of employment in their current company. The theoretical model was tested through gathering data from employees working in the financial services sector, where the employees stated assessments regarding the actions of their leaders, their selves, and respective company. The data were used to test the relationship between the independent variables and dependent variables, as well as the moderating variable.
The results of the assessments displayed that a substantial connection is obvious with regard to implementing a transformational leadership approach to strengthen the impact of environmental and ethical CSR on organizational goals. Our findings correspond with the existing research on transformational leadership and environmental and ethical CSR [113,114]. For instance, the study of Graves et al. [115] enabled an opportunity for global comparison with China, where it was similarly established that a direct, positive link between transformational leadership and employees' environmentally responsible behavior is apparent. Similarly, transformational leadership was established to enhance environmental performance in the United Arab Emirates (UAE), based on a study conducted on SMEs operating in the manufacturing sector [116]. One way of deliberating our results is that the individualized consideration aspect of the transformational leadership approach enables leaders to communicate personally with every employee, leading employees to take more sensitive actions towards other stakeholders in return. Moreover, the inspirational motivation approach characteristic improves the determination of employees to fulfill organizational goals.
Furthermore, a noteworthy aspect of our findings was that the positive effect of transformational leadership was more than twice as high on ethical CSR (0.688) in comparison to environmental CSR (0.255). These findings conceivably refer to conceivable notions that the ethical aspect of our questionnaire's statements was presenting the organizational standpoint with examples such as "We are recognized as a trustworthy company", whereas the environmental aspect had personal statements such as "I print double sided whenever possible". Therefore, having organizational guidelines led employees to internalize ethical actions at an additional level than environmental ones.
Furthermore, the findings of our study presented that implementing the transactional leadership approach likewise had a positive effect on environmental and ethical CSR. These outcomes are parallel with our Hypotheses 1 and 2, as well as the part of the literature, agreeing with the influential aspect of transactional leadership on CSR activities [15,78,80]. On the other hand, it is in contrast with the studies stating there is no effect between the independent variable and dependent variables [117]. As an example, Ng and Burke [118], on the contrary to this study, did not establish a statistically meaningful link between transactional leadership and sustainable actions. However, this study was conducted on business students residing in the United States. Transactional leadership (0.187) had less influence on environmental CSR in comparison to transformational leadership (0.255). This might relate to the cross-culturally self-directed nature of the transformational leadership approach on subordinates' autonomous motivation [119], whereas transactional leadership operates certain reward and punishment systems. In addition, there was no reward or punishment on these explorations of environmental CSR statements, such as "I bring reusable utensils to work (e.g., coffee mug, reusable containers)". On the other hand, the effect on ethical CSR was more apparent (0.745) in comparison to transformational leadership (0.688). This can likewise be understood by the reward-punishment system, since breaking ethical CSR statements like "Fairness toward co-workers and business partners is an integral part of the employee evaluation processes" would produce undesired outcomes for employees. Nevertheless, this does not mean that transformational leaders would not punish undesirable behavior, but a clear punishment procedure might lead employees to take improved ethically responsible actions to some extent.
In addition, our findings on the hypotheses with regard to the moderating variable provided diverse results. Hypotheses 5, 7 and 8 were rejected, as employees' years of employment did not have a moderating effect on the relationship between transformational leadership and environmental CSR, as well as transactional leadership with environmental and ethical CSR. The moderating effect was positively visible only on the relationship between transformational leadership and ethical CSR. Although previous studies highlighted the importance of employee tenure on certain organizational objectives [96][97][98], our results suggested the contrary except for ethical actions of employees operating under transformational leaders. However, since all of the relationships between the independent variables and dependent variables are positively correlated, the lack of a moderating effect could be interpreted as employees already adopting certain behaviors during the initial time working with the leaders and retaining it at a steady level as years passed.

Implications
This investigation provides substantial contributions to theory and practice mutually, on leadership and corporate social responsibility aspects of organizations. The research empirically assesses the model on the influence of transformational and transactional leadership approaches, as well as the positive moderating impact of employees' years of employment in the current company, on environmental and ethical corporate social responsibility. The research indicated that organizations in the financial services sector can improve environmental and ethical aspects of corporate social responsibility through using both transformational and transactional leadership theories. This specifies that the offered model is an advancing approach in better comprehension of CSR. Such findings contribute to the research topic in the sense that transformational leadership was more influential on environmental CSR, where transactional leadership had a superior effect on the ethical aspect of CSR. Adopting these data as the starting point on leadership and CSR can also lead the researchers to examine which components of each leadership style lead to these changes between environmental and ethical CSR. Furthermore, the outcomes of this study contain additional managerial implications that can support leaders while setting socially responsible objectives for corporations. Transformational and transactional leadership approaches can be used complementarily to benefit from increased advantages. For instance, a leader who effectively combines the individualized consideration aspect of transformational leadership and contingent reward aspect of transactional leadership can convince the employees that multiple effects of actions should be considered simultaneously. The contingent reward aspect would present the employees a clear pathway into following guidelines to benefit the business, while the individualized consideration of each employee would assist in clarifying the vision behind such actions, as well as creating a sense of value. It is believed that the leadership approaches should be used interdependently to achieve such lasting outcomes.
In addition, our study can benefit shareholders in the sense of improving financial performance through CSR, since there are positive links between corporate social responsibility and awareness in relation to financial performance [120,121]. Precisely, Ali et al. [122] collected data from 229 companies in Pakistan suggesting that developing a positive image amongst stakeholders through CSR lowers overall costs, and improves financial performance. Thus, certain conflicting objectives with the shareholders can be viewed from this perspective by signifying that investment in CSR can lead to higher profit generation in the long term both directly and indirectly, through profits and brand image, respectively. Once the suitable approaches of leadership are implemented, stakeholders such as the society, customers, and employees can benefit from ethical and environmentally responsible actions, and shareholders can benefit from such enhanced financial gains. In this context, implementing the appropriate leadership styles is the key point of aiming to maintain the balance between implementing CSR practices and satisfying shareholder goals.
Accordingly, it is also worth noting that the previously mentioned concept of "green bonds" [26] is receiving increasing consideration from practitioners and scholars [123,124]. The revenues of green bonds are used to fund an extensive range of activities such as sustainable change management and climate adaptation [125]. Thang and Zang [126] advocates that corporations' issuance of green bonds is beneficial to their existing shareholders. Therefore, the leaders of companies in the financial services industry can look towards green bonds as an effective way of implementing corporate social responsibility actions without compromising financial gains.

Conclusions
The importance of suitable leadership styles is recurrently highlighted, with the intention of creating desirable outcomes for stakeholders. Such intentions include environmentally and ethically responsible actions. The leadership styles chosen for this study were contemporary theories of transformational and transactional leadership, with the purpose of examining their impact on environmental and ethical CSR. The moderating effect of employees' years of employment in their respective companies was investigated as well. Our conclusions are that both of the independent variables had a statistically meaningful effect on dependent variables, and the moderating variable only had a positive effect on the relationship between transformational leadership and environmental CSR. In contrast, employees' years of employment did not have a moderating effect on the relationship between transactional leadership and dependent variables, as well as on the relationship between transformational leadership and ethical CSR.
As transformational and transactional leadership both had positive effects, but on different levels depending on environmental and ethical aspects of CSR, it can likewise be concluded that an effective combination of the two leadership styles can lead to improved results. The study also concludes that using appropriate leadership styles in companies operating in the financial services industry of the UK can improve the organizations' ethically and environmentally responsible actions towards stakeholders.

Limitations and Further Research
One limitation of this study is the singular focus on the financial services industry in the UK, meaning that the findings of the study are challenging to generalize in dissimilar business contexts. For that reason, replicating the study in different industries and countries can be attempted in future studies. As an example, replicating this study through focusing specifically on FinTech companies (e.g., crowdfunding, block chain) can potentially provide interesting outcomes for comparison. Moreover, although there has been extensive research on the research area, there is still room for further research. As leadership and corporate social responsibility are greatly comprehensive concepts, different approaches of leadership and CSR can be investigated with the aim of measuring additional correlations between the two concepts. Ketola [127] concluded that the approach of visionary leadership implemented interdependently with coherency creates desirable CSR outcomes. This approach can be tested by focusing specifically on the environmental aspect of CSR, which would be relevant while facing the climate change issues of the current pandemic era. As a final point, as opposed to the employees' perspective of the leaders and their selves, further research can measure the same topic from the leaders' perspective on their selves and employees.
