Empirical Research in Colombian Services Sector: Relation between Transformational Leadership, Climate and Commitment

The objective of this study is to analyze the relationship between the variables of transformational leadership, climate and commitment in a sample of 319 workers of a multinational organization in the Colombian Services Sector. For data collection, we used the Multifactor Leadership Questionnaire (MLQ), the climate/culture questionnaire FOCUS-93 and the Intellectual, Social and Affective Commitment Scale (ISA). Data were processed with SPSS 23 and AMOS 22 for modeling with structural equations. In the path diagram, calculated according to the indicators of structural adjustments, variances were obtained for the dimensions of organizational commitment. The resulting model presented favorable adjustment indicators as evidenced in the results, and the relationship between commitment and climate was significant (β = 4.61; p = 0.001), as well as between climate and commitment (β = 0.018; p = 0.001). However, the relationship between transformational leadership and commitment was not direct but mediated through organizational climate.


Introduction
The current crisis generated by the COVID-19 pandemic has highlighted the importance that world leaders have in creating favorable climates in their countries/organizations to achieve the commitment of citizens/workers regarding compliance with the security protocols established to safeguard lives. Various investigations have managed to identify the direct, positive and significant relationship of these three variables (leadership, climate and commitment) in matters of safety, since the leader, with managerial and technological tools, enables the fundamental safety climate for workers to commit themselves to adopt practices and comply with safety protocols and standards [1][2][3][4][5][6][7][8]. Reviewing the research, it was also observed that transformational leadership generates a supportive climate and increases commitment [9][10][11][12][13][14][15][16][17][18][19].
The concept of transformational leadership was introduced by Burns [20] and, subsequently, Bass and Riggio [21] expanded his study. These studies converted transformational leadership into a new paradigm when speaking about leadership. According to Bass and Riggio [21], transformational leadership consists of the following dimensions: idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration. Idealized influence refers to the degree to which the leader's example, the impeccable actions, and his quality of life make collaborators perspectives of human resources systems. Social commitment allows the collaborators a connection by sharing common values in their working environment [50][51][52].
Furthermore, according to Soane et al. [53], among the commitments are (a) the intellectual one, which implies empowerment and the approach to release cognitive effort towards the objective achievement or the solution to a challenge; (b) positive affection which has the role of encouraging the thinking process [54]; (c) affective commitment which enables positive affect [52,55]; (d) social commitment which requires initiating and maintaining the social interactions related to work, as well as demands and active commitment with other people [56]. Thus, affective commitment is significant for a variety of positive results related to the improvements and construction of personal resources [54]. The intellectual commitment is relevant to performance as well as other results such as innovation [57]. Social commitment could be particularly relevant for the organizational change since social effective processes are essential for the positive change results [49].
Research studies by Economist Intelligence Unit [58] stated that when the voices of employees were heard individually, and the obtained information was used as a transformational mechanism to optimize the development of the organization, the employees were more willing to meet the work commitments and remain. Likewise, Kwon, Farndale and Park [59] stated that when employees are heard, they perceive management oversight more lawfully because the decision-making in relation to work is guided by those who carry out the work directly. Chernyak-Hai and Tziner [4] showed how organizational climate mediates even the relationship between company commitment and a worker's personal values. Martínez-Córcoles and Stephanou [6] and Tappura, Nenonen and Kivistö-Rahnasto [5] found that organizational climate quality influences positively on workers' commitment. Finally, Totin, Roncoli, Traoré, Somda and Zougmoré [60] concluded that institutional identity is a commitment indicator in relation to participation climate in the organization, and configures the organizational capability to achieve the objectives.
On the other hand, the strong relationship between transformational leadership and organizational commitment was described by authors such as Jena, Pradhan and Panigrahy [61] who referred to the positive transformational leadership effect on the commitment of the employee and on organizational confidence. Pradhan and Pradhan [62] found that in a group of workers, there was a causal effect between the existence of transformational leaders in the organization and the development of significant work at a high commitment level; Buil, Martínez and Matute [63] also observed in a sample of Spanish employees that transformational leadership was supplied by work commitment.
Yukl, O'Donnell and Taber [64] noticed in their studies that companies which have transformational leaders present higher levels of organizational commitment. Similarly, Ding, Li, Zhang, Sheng and Wang [65], showed how transformational leadership is positively related with employees' work commitment, particularly with leadership factors, inspirational motivation, and idealized influence or charisma. Although generally a relation between leadership, climate, and commitment has been empirically evidenced, Amah [66] stated that the relation between leadership style and employee commitment is not direct but mediated through variables that arise from the environment created by leadership behavior. According to this approach, the relationship between those variables is given in such a way that transformational leadership presence positively affects organizational climate, and the variation of this contributes on organizational commitment, that is, climate is the mediator of the relation between leadership and commitment.
This paper is consistent with others published in different countries, which are more and more relevant in transformational leader training, with their valuable contribution to improve organizational climate and collaborative commitment, making possible a greater competitiveness among companies and a better quality of life for their workers. Our study contributes to the current literature since there are no works studying the detailed relationship between the three variables, especially in relation to the measured relationship.
This study presents the same relational structure with the mediator role of organizational climate as a nexus between transformational leadership and organizational commitment, as shown in Figure 1.
It becomes especially evident in studies such as those by De Clercq and Rius [67], Gözükara and Faruk Sùimúek [68] and Gyensare, Kumedzro, Sanda and Boso [69]. However, there are few works in the Colombian context that focus on studying the relationship between these terms. According to the empirical findings mentioned, the current research proposed as its objective to identify the relation between transformational leadership, climate, and organizational commitment in a multinational company in the service sector in Colombia.
First, we intend to study the relationship between transformational leadership and organizational climate in the service sector of a Colombian multinational company. There are very few works that study these variables in a Colombian cultural context. Previous literature supports the positive effects that transformational leadership has on organizational climate. There is some research that shows the relationship between these variables and, in this line, we can find the works by Cuadra-Peralta and Veloso-Besio [27], Zohar and Luria [26] and Ortíz and Castaño [29]. These authors validate the relation between transformational leadership and work climate [26,27] considering that the collaborators who have a transformational leader perceive a positive climate. Thus, on the hypotheses of the previous literature we propose the following ones: Hypothesis 1. There is a positive and significant correlation between the variables of transformational leadership and organizational climate.
Secondly, we are interested in knowing if the role of the leader is essential to get Colombian workers committed to the organization. Previous research shows the causal relationship between these terms, specifically the causal relationship between leadership and commitment, is essential in the organization. We support our work in the investigations carried out by Jena, Pradhan and Panigrahy [61], Pradhan and Pradhan [62] and Buil, Martínez and Matute [63]. It is important to note that these authors proved that they referred to the positive transformational leadership effect on the commitment of the employee. Based on this, the following hypothesis is proposed: There is a positive and significant correlation between the variables of transformational leadership and organizational commitment.
Thirdly, we are interested in studying the relationship between organizational climate and commitment of Colombian workers. Our research is supported by the works of Eldor and Harpaz [70], Powell, Davies and Norton [71], Martínez-Córcoles and Stephanou [6] and Tappura, Nenonen and Kivistö-Rahnasto [5], since these authors validate that climate positively influences commitment of workers and that organizational climate quality influences on workers' commitment. The prevailing evidence suggests the link between both variables. So, our hypothesis proposal is as follows: There is a positive and significant relationship between the variables of organizational climate and organizational commitment.
Fourthly, there are few works that focus on studying the relationship between leadership and worker commitment measured by organizational climate. It should also be noted that there are no previous investigations in Colombia. Interested in these variables, we will explore this mediated Transformational Leadership Organizational Climate Organizational Commitment According to the empirical findings mentioned, the current research proposed as its objective to identify the relation between transformational leadership, climate, and organizational commitment in a multinational company in the service sector in Colombia.

Fourthly, there are few works that focus on studying the relationship between leadership and worker commitment measured by organizational climate. It should also be noted that there are no previous investigations in Colombia. Interested in these variables, we will explore this mediated relationship in more detail, performing a more robust analysis of structural equations. We support this hypothesis in the approaches of Ford and Seers [72], Wu et al. [73], Dahl and Olsen [74], who found the mediation of climate, whereas Amah [66] pointed out the need to promote work in this direction; specifically, as we have previously explained, this author establishes that the relationship between leadership and commitment is mediated by organizational climate. Our hypothesis is as follows: Hypothesis 4 (H4). The variables of transformational leadership and organizational commitment are related to the mediation of organizational climate.
In this situation, this article has theoretical contributions to the existing literature, since it starts from a previous line of work related to the studied variables. Regarding the additional values of this study, we would like to highlight that this is a novel investigation carried out in Colombia in the service sector. On the other hand, concerning theoretical contributions, we want to stress that it checks the validity of a theoretical model reflecting the solid relationship between the variables studied.

Participants
The sample was composed of 319 participants, aged between 20 and 60; 186 (58%) of the study participants were men and 133 (42%) were women. Regarding the time they had been employed at the company, 198 people (62%) were there longer than 3 years, 73 had been there 1-3 years (23%) and 48 had been there less than 1 year (15%). According to age, 44% corresponds to people aged between 31-40, 29% between 20-30, 22% between 41-50 and 5% between 51-60. Respecting the kind of work of the population surveyed, 27% were general service leaders, followed by 18% of general service coordinators, 17% were shift managers, 14% maintenance leaders, 13% leaders of other areas and 11% were maintenance professionals. They all worked in different cities of Colombia, most of them in Bogotá (34%) and Medellín (32%) and the rest (34%) worked in Cali, Barranquilla, Cartagena, Bucaramanga, Eje Cafetero and Neiva.

Instruments
To assess transformational leadership, we used the Multifactor Leadership Questionnaire (MLQ) of Avolio and Bass [75]. This questionnaire assesses transformational leadership through 4 dimensions and a total of 15 Likert-type items, whose scale goes from totally disagree (=1) to totally agree (=7) (e.g., it says positive features about the department/area), with an internal consistency of Cronbach's alpha (Cronbach alpha = 0.928).
The organizational climate assessment was done by means of [34] FOCUS-93 (First organizational Climate/Culture Unified Search) questionnaire in its short version. This instrument measures climate with 4 dimensions and a total of 12 Likert items whose scale ranges from totally disagree (=1) to totally agree (=7) (e.g., it puts into practice new ideas to improve work and its results). Internal consistency is measured with Cronbach's alpha (Cronbach's alpha = 0.895).
The organizational commitment was assessed by means of the Escala de compromiso Intelectual, Social and Afectivo (ISA) by Soane et al. [53] in the Spanish version of Mañas et al. [37]. This scale evaluates the commitment in 3 dimensions with 9 Likert-type items whose scale ranges from totally disagree (=0) to totally agree (=6) (e.g., I share the same work values as my partners). The internal consistency was measured with Cronbach's alpha (Cronbach's alpha = 0.844).

Procedure
In the first place, a letter was sent to a multinational company in the service sector requesting its collaboration, specifying the research features and the commitment to confidential data treatment. Secondly, the human resources section sent an e-mail to each collaborator indicating the objective of the study and the importance of their participation and collaboration to answer the scales on a voluntary basis. We agreed on how much time (15 days) to complete online the 3 questionnaires (MLQ: leadership, FOCUS: climate, and ISA: commitment), which comprised a total of 45 questions to be answered in 15-20 min. After that, the human management area reviewed the information online. Then, the information was incorporated into an Excel sheet and the structural equations were modeled with [76,77] IBM SPSS Statistics version 23, and AMOS 22.

Data Analysis
Data were prepared reviewing the normal data distribution and verifying that the indicators of asymmetry and kurtosis were in admissible ranges to assume the multivariate parametric models. It was perceived that affective and intellectual commitment values presented anomalies in distribution, showing extremes to be corrected. Therefore, it was resolved carrying out a transformation to z scores to correct the distribution of the variable and to carry out a subsequent statistical analysis.
Once the database was adjusted, we analyzed the correlations between the study variables to examine, with the r of Pearson, the relation between transformational leadership, organizational climate, and commitment.
AMOS was generated to confirm the relationship between the variables of transformational leadership, organizational climate, and commitment. It is an exploratory path that allows the analysis of this interaction, establishing higher and meaningful relations between leadership and climate, such as between climate and commitment but not in regard to the expected association between leadership and commitment. In such a way, it presents a regression model to identify the nature of relations between these variables, considering an indirect causal relation where the association between leadership and commitment is measured by the climate variable.
According to the above, it processed to set up a theoretical model of indirect relation. For this purpose, a Structural Equational Modeling (SEM) was designed with a statistic model of Maximum Likelihood (ML) with AMOS 22 software.

Results
The information obtained was analyzed, both with the SEM and with descriptive statistics. As a previous step, a confirmatory factor analysis was performed (see data in Table 1). In Table 1 appear the statistically meaningful correlations between leadership and organizational climate (r = 0.681, p < 0.01); although minors in leadership and commitment (r = 0.239, p < 0.01), X established a meaningful theoretical model between organizational climate and commitment (r = 0.412, p < 0.01); these values do not present scores higher than r = 0.90 and they are established as indicators of multicollinearity absence between variables, a precondition to multivariate analyses used with path analysis and structural equations. Using the information obtained from the Structural Equations Modeling (SEM), the observable and dormant variables are observed as conformed by the dimension on each construct (Figure 2). The obtained model was calculated according to the indicators of structural adjustments, the kindness absolute fit variables; and the use of the reason index χ 2 (Chi square with its p-value) is recommended to indicate the predictive capacity of correlatives-plausibility matrix, given the χ 2 is sensitive to sample size and other factors as the number of χ2/DF (Chi squared over freedom degrees) that should be below 3; at the same time, values higher than 0.90 are expected preferably above 0.95 to CFI (Comparative fit index), GFI (Goodness Fit Index), AGFI (Adjusted Goodness Fit Index), TLI (Tucker-Lewis Index); and values below 0.08 in [78] RMSEA (the Root Mean Square Error of Approximation) indicates a minimum error of approximation of the model to the data obtained [79]. The adjusted values obtained are in Table 2.  The resulting structural relation model, according to the adjustment indicators, is shown in Table  2. Variances were obtained and explained for the dimensions of organizational commitment. According to transformational leadership, the measures with ISA were between 0.18 and 0.96, and organizational climate with 0.80. The obtained values in the predictive analysis agree with the unstandardized estimated regression values obtained from AMOS 22 (See Table 3), given with respect to the study hypothesis of leadership as a climate predictor (β = 0.461, DE = 10.895, p = 0.001). Likewise, climate is a commitment predictor (β = 0.018, DE = 6.125, p = 0.001), as it evidences that the effect between leadership and commitment occurs through climate. On the other hand, the R2 factors for climate and commitment were 0.45 and 0.52, respectively. Finally, a review is made about direct, indirect, and total effects of the three variables that integrated the proposal model. As noted in Table 3, leadership has an important director climate effect; so, if the first variable increases in a standard deviation, the second one increases in 0.802, similarly in 0.0441 concerning climate and commitment. These direct effects have, as a consequence,  The resulting structural relation model, according to the adjustment indicators, is shown in Table 2. Variances were obtained and explained for the dimensions of organizational commitment. According to transformational leadership, the measures with ISA were between 0.18 and 0.96, and organizational climate with 0.80. The obtained values in the predictive analysis agree with the unstandardized estimated regression values obtained from AMOS 22 (See Table 3), given with respect to the study hypothesis of leadership as a climate predictor (β = 0.461, DE = 10.895, p = 0.001).

On the other hand, the R2 factors for climate and commitment were 0.45 and 0.52, respectively. Finally, a review is made about direct, indirect, and total effects of the three variables that integrated the proposal model. As noted in Table 3, leadership has an important director climate effect; so, if the first variable increases in a standard deviation, the second one increases in 0.802, similarly in 0.0441 concerning climate and commitment. These direct effects have, as a consequence, a direct effect between leadership and commitment, in such a way that the standard deviation increases in the first one and added increase to the second in 0.353 standard deviations.
The proposed model was developed looking for the higher explanatory level that could be possible between variables, given as a result that a model does not contemplate the direct interrelation between the three variables, but it is mediated by work climate behavior in the organization.

Discussion
The present study uses the correlation analysis to explore potential relations between constructs and subscales of the study variables, and it uses structural equations as statistical analysis techniques as a multivariate alternative that serves to contrast the relation of the proposal model between the variables of transformational leadership, climate, and organizational commitment.
The first hypothesis was contrasted with the correlational analysis confirming the relationship between the two study variables, proving a meaningful correlation between transformational leadership and organizational climate with an r value of 0.681. Likewise, hypothesis 2 was verified by means of meaningful correlations between transformational leadership and organizational commitment with an r value of 0.239. As regards to hypothesis 3, looking for the relation between organizational climate and organizational commitment, it also presents a meaningful and high relation with an r value of 0.412.
When analyzing the values of the subvariables, a positive and high relation between the affective commitment variables and organizational climate was obtained, being the subvariable with the higher value of correlation. On the other hand, the organizational commitment variables have higher correlation values with the other transformational leadership subvariables.
To make the analysis needs to check out hypothesis 4, the particular analysis of interaction between the three variables confirmed the relation between transformational leadership and organizational climate, and between organizational climate and organizational commitment, and it does not prove a meaningful relation between transformational leadership and organizational commitment, which was necessary to develop a model based on confirmed relations and to explore a potential mediating effect between transformational leadership and organizational commitment. So, regarding the relation between transformational leadership and climate, it is evident that the variable effects on the organizational climate perceptions of its collaborators, such as numerous authors had reported beforehand [80]. In regard to the relation between climate and commitment, it is reaffirmed the exposed by Chernyak-Hai and Tziner [4], Tappura, Nenonen and Kivistö-Rahnasto [5], Martínez-Córcoles and Stephanou [6] and Totin, Roncoli, Traoré, Somda and Zougmoré [60], who had expressed that organizational climate has a positive effect on workers' commitment.
However, the mediation model template presented favorable adjustment indicators as it was evidenced in results, according to which, leadership acts as an organizational climate predictor, and this as commitment predictor, showing in the first place the meaningful associations between these variables and, secondly, the mediator effect on the climate variable in respect to the relation between transformational leadership and organizational commitment, confirming the previous findings reported by Payne,and Pugh [81], Kopelman, Brief and Guzzo [82], Gözükara and Faruk Sùimúek [68] and Gyensare, Kumedzro, Sanda and Boso [69].
Regarding the role of the mediator of organizational climate in the relationship between transformational leadership and organizational commitment, it is worth delving into the remark made by Menges, Walter, Vogel and Bruch [9], who confirmed the results found in this study. On the other hand, De Clercq and Rius [67] discovered that affective relationships born from climates increase the presence of organizational commitment behaviors because, according to the authors, the organization's perception of interest in providing a positive experience makes the worker want to be mutual, offering a greater commitment to the institution. These approaches prove how climate acts as a mediator between organizational commitment and transformational leadership. In this sense, it is essential that employers try to promote a positive and achievement-focused climate in the workplace so that workers feel more committed to the work they do.
Given that the structural equation models are based in the existent correlation between variables in a sample of subjects in a transversal way, as performed in this case with the multinational services company, also emphasizes for its social responsibility programs. It can be concluded that for this kind of organization, it is favorable to rely on transformational leaders because these create a positive climate and greater collaborator commitment that is recommendable when a company wishes to work with inclusion and to contribute with peace and conciliation. It should be noted that the added value in the current work has validated the relationship described in a Colombian sample of a multinational company in the service sector.
However, it is of particular interest to the investigative exercise to consider in depth the findings with respect to the mediator role of the organizational climate variable [83]. This represents a potential field analysis as to action and impact spectrum that could be the climate in different organizational variables, and the interaction between them. Likewise, for the particular processes promoting from this, a study of Ngo, Foley and Loi [84] reported the mediator role of organizational climate between work friendly practices and organizational efficiency. Messersmith, Patel, Lepak and Gould-Williams [85] indicated that organizational climate mediates the connection between human resources practices, and job innovative performance. In the same way, Yasir, Imran and Kashif Irshad [86] reported a significant relationship between job performance and individual consideration, mediated by organizational climate. Green, Albanese, Cafri and Aarons [14] declared in their analysis that climate is an effective mediator between leadership and work alliances; and Nelson, Boudrias, Brunet, Morin, De Civita, Savoie and Alderson [87] found that climate mediates relations between leadership and work well-being. In this way, workers will be much more involved in the work if they perceive some support from the business organization.

Limitations and Future Directions
Among the principal limitations of this work is the fact that the sample belongs to a multinational company located in Colombia and, in this sense, the findings can only be extrapolated to the Colombian population. To exceed this limitation, it would be advisable to review studies in other countries with the same variables of transformational leadership, organizational climate, and organizational commitment. It is recommended to continue exploring in other organizations committed with social responsibility. In addition to the cultural limitation that we have just mentioned, in our opinion, there is another limitation that should be highlighted; this is a cross-sectional investigation, that is, the results are conditioned by the time point in which the questionnaire was applied. In this sense, if we intend to generalize the results, we will need to promote longitudinal studies and to extend them to private, public, and NGO organizations of any kind, and to other countries. Besides, in order to offer more detailed explanations, we suggest to consider other variables, such as stress and human capital, to complete the social capital of organizations to emphasize the social commitment (SC) since it was the single variable that was not meaningful in the leadership indicator. Finally, this study uses cross-sectional data to test the mediation model [88].

Practical Implications
Our work makes an important scientific contribution, since it offers a scientifically supporting theoretical framework that could guide organizations to know what variables to work with if they intend to engage their workers. On the other hand, in order to contribute from the applied research, it could be useful for groups of leaders to develop skills as transformational leaders; to make comparative studies between transformational leaders; for those who have not received training, it would be effective to create transformational leader groups to train them; and determine the correlation with organizational climate and workers' commitment in creating experimental and control groups in the same organization to review positive occupational psychology techniques, making possible those advances. With these findings, the importance of transformational leaders' work at organizational level could be more and more substantiated.
Therefore, this current research contributes for those who manage human resources to recognize the importance of increasing the commitment of employees, as stated in previous researches [74,75]: Employees with more commitment will have a better performance in their jobs, and will increase their effort and motivation as well as their positive cycle of emotions and cognitions. Performance, innovation, organizational citizen behaviors and their positive attitude towards change will improve, whereas rotation will be reduced.

Conclusions
From a corporate point of view, the significance of this article refers to the following scientific contributions: First, there will be a validated theoretical model showing the relationships between these variables in a given sociocultural context. Second, the joint analysis of variables that until now had been partially studied, was proposed in this article to verify the short-term relationship between variables. Finally, as previously mentioned, there are few studies that carry out mediation analyses in relation to the organizational climate in a Colombian sample. Therefore, this work will offer a general and scientific overview of the mediated relationship.
In summary, this research offers an empirical support that tries to clarify the relationships between worker commitment, transformational leadership, and organizational climate. Furthermore, the decisive role that the leader has to commit Colombian workers has been explained in a robust way. Additionally, it has been verified that the most effective leadership style to achieve organizational commitment of Colombian workers is transformational leadership. Finally, if in the Colombian context we want to retainworkers, it is necessary to keep in mind the profile of the transformational leader and the type of organizational climate.
