1. Introduction
Workplace accidents are generally regarded as a major concern in terms of occupational health and safety (OHS). According to International Labor Organization estimates, at a global level, 340 million employees are victims of workplace accidents every year [
1]. Statistics on occupational accidents in Turkey reveal similar results. Official data indicate that in the past decade over 12,000 workers died in occupational accidents in Turkey [
2]. In comparison with the European Union, the fatal occupational accident rate in Turkey (per 100,000 workers) is approximately seven times higher [
3]. Therefore, there is a stringent need for research on strategies for improvement of workplace health and safety performance in Turkish companies, considering that prevention of accidents and risks in the workplace is the basis of occupational safety.
Romania (2009–2016) was consistently at the top of the EU ranking with a high rate of work fatal accidents, ranging from 9.9 to 4.7 per 100,000 workers [
4,
5]. In comparison with Romania, Turkey has an annual rate of work fatal accidents varying between 1.5 and 2 per 100,000 workers. Considering the most recently available national statistics in 2020, Turkey has a total of 1231 work fatal accidents [
6], and Romania only 143 [
7]. In terms of nominal figures, Turkey has almost 10 times more fatal accidents, but the nominal figures must be reported per 100,000 workers. Considering that Turkey has 27.07 million workers [
8] and Romania has only 5.16 million workers [
9], we arrive at a fatal accident rate per 100,000 workers of: 4.55 for Turkey vs. 2.77 for Romania, observing almost twice as many fatal accidents in Turkey.
Moreover, there is an increasing focus on identification of solutions through research on the causes of occupational accidents. While research shows that many individual and situational factors [
10] play a significant role in occupational accidents, the unsafe behavior of employees is often emphasized as the main cause of occupational accidents [
11,
12]. From human error to non-compliance with health and safety instructions and practices, risk factors specific to the human operator are subjective factors, generating occupational accidents and illnesses. Considering this, research on ‘unsafe behavior’ has gained momentum in recent years. Interest in the concept of safety leadership has increased in recent decades, as safety leadership is accepted as an important antecedent of employees’ safety perceptions, attitudes, and behaviors [
13]. Previous research demonstrated that the strong connection between safety learning (understood as employees’ opportunity to learn from their own errors and compliance omissions in order to improve safe behavior) and safety participation is the result of leaders’ supportive behavior [
14]. Safety leadership was also proven to be more effective when characteristics of transformational leadership behavior were manifested [
14].
To achieve workplace safety, an essential organizational factor is safety climate. The importance of safety climate is considered in the context of employees’ unsafe behavior (i.e., employees’ behaviors leading to exposure to risks of accidents and occupational disorders). Therefore, research on safety climate revealed a positive connection between employees’ safe behaviors and their perceptions of occupational safety [
15,
16,
17,
18,
19,
20]. On the same note, studies on occupational safety and health in Turkey’s companies indicate an increasing interest in the relationship between safety climate and safe behaviors, revealing that leadership behavior has a considerable influence on increasing safety in the workplace [
21,
22,
23,
24]. For example, Sadullah and Kanten [
22] demonstrate a positive relationship between safety behaviors and management practices such as training on the use of personal protective equipment and safety protocols, a positive psychosocial environment and frequent maintenance and repair work (to reduce the risk of using faulty machinery and equipment). However, a limited number of studies have been conducted in the direction of safety leadership [
25,
26].
Moreover, safety climate was proven to have a mediating role in the effect of safety leadership on employees’ safe behaviors [
27,
28]. Data show that fatal occupational accidents are considerably high in Turkey and Romania, ranking as the leading European countries by number of fatal accidents [
29]. Despite the fact that the role of safe behavior in occupational accidents is an important research topic, there is a research gap in studying the connection between safe behaviors and safety climate in Turkey and Romania. Therefore, the main contribution of this study is to fill this gap in the literature and guide future studies to be carried out in the field of occupational safety.
Finally, the COVID-19 pandemic, which frightened the world in 2020, forced many manufacturers from both Europe and the world to experience supply chain problems. One of the striking effects of the pandemic was the understanding of the importance of geographical proximity in the production process. Accordingly, the fact that China was the sole and most important producer put some countries at risk. On top of all these developments, Russia’s invasion of Ukraine caused the supply chain and production problem to be much more serious. For these reasons, companies started to look for new places for production chains, and manufacturers, who moved away from China and Ukraine, started to feel interested in countries with a production culture and proximity to Europe. such as Turkey and Romania. Therefore, it has become important to examine the occupational safety culture in these countries sensitively, and for these reasons this study was designed.
4. Results
Before testing the hypotheses, it is important to show a statistical comparison of the safety climate, transformational safety leadership and safe behaviour in the two countries. Since variables are not normally distributed, a Mann-Whitney U test was performed to analyse the national differences for the relevant variables.
Table 2 shows the nationality comparison analysis results.
According to
Table 2, it is concluded that there are no statistically significant differences between safety climate, transformational safety leadership and the safe behaviour of Turkish and Romanian employees (
p > 0.05). From this point of view, the safety climate, transformational safety leadership and safe behaviour perceptions of the two countries are statistically similar.
Table 3 shows the descriptive statistics for the variables and the correlation results between these variables. As per these results, the mean values are: safety climate, 3.70 (±1.02); transformational safety leadership, 3.52 (±1.01); and safe behaviour variable, 3.80 (±0.94), respectively. When the correlations between the variables were examined, it was observed that there was a strong and significant relationship between the safety climate and transformational safety leadership (r = 0.716;
p < 0.01), moderately strong and significant relationship between the safety climate and safe behaviour (r = 0.683;
p < 0.01), and a moderately strong and significant relationship between transformational safety leadership and safe behaviour (r = 0.669;
p < 0.01). On the other hand, since the inter-correlations between the variables are below 0.90, it is seen that there is no common method variance [
81].
The results of the mediation model established in the research are shown in
Table 4.
The model constructed according to
Table 4 is significant (F = 122.43;
p = 0.00). Furthermore, since the lower and upper confidence intervals in the established mediation model do not cover zero value [
74,
77,
79,
80,
82,
83], the mediation effect can be considered significant (Lower = 0.0825; Upper = 0.3684; Sobel Z = 5.3335;
p = 0.00). Furthermore, in the Preacher and Hayes’ mediation model, the explanatory power of the model will decrease due to measurement errors. In this case, the significance of the confidence intervals and standard errors of the residuals are evaluated for the significance of the model rather than the statistical interpretation of R
2 [
84]. So, when using the bootstrapping resampling method, report percentile, bias-corrected, and acceleration confidence interval were considered to obtain the most robust results for assessment of mediator and indirect effect. In this study, only the bias corrected confidence interval results were included, as the results of the analysis were supported by the three results’ reports.
As per
Figure 5, Hypothesis H1 was validated and transformational leadership had a positive effect on the safety climate (β = 0.6457; t = 13.97). According to the results, a one-unit increase in transformational leadership increases the perception of a safe environment by 0.65 units. The analysis also confirmed Hypothesis H2, as transformational leadership positively affects safe behaviour (β = 0.5876; t = 13.78). Accordingly, the employees’ perceptions of transformational leadership increase employees’ safe behaviour tendencies by 0.59 units. Another finding confirming Hypothesis H3 is that the safety climate positively affects safe behaviour (β = 0.2989; t = 5.77). Consequently, an increase in the perception of safety climate increases employees’ probability of safe behaviour by 0.30 units. When all the results obtained were evaluated, transformational leadership was found to improve the climate of safety and safe behaviour. This leads to the conclusion that the safety climate also improves safe behaviour. Finally, it was observed that the safety climate had a partial mediating role between transformational leadership and safe behaviour (β′ = 0.3946; t = 7.52; Sobel Z = 5.3335;
p = 0.00) (Hypothesis H4). Consequently, the safety climate has a partial mediating role in the relationship between transformational leadership and safe behaviour (See
Table 5). Furthermore, there is no multicollinearity problem since the correlation values between variables is below 0.80 and the VIF values below 2 [
79,
84,
85]. In other words, transformational leadership affects the safety climate, which in turn affects employees’ safe behaviour.
5. Discussion
OHS is vital for proper working conditions and a high employee retention rate [
84]. Not only are these safe behaviours a means of ensuring workplace wellbeing, but transformational safety leadership enables the achievement of corporate sustainability goals. Research results show that transformational safety leadership is positively related to both safety climate and safe behaviour. Leaders who are concerned about the safety and well-being of their employees and who support their values and beliefs about the importance of safety will generate the manifestation of safer behaviours among employees. This result is supported by the literature showing that transformational leadership positively contributes to safe behaviours [
44,
55,
56]. In addition, transformational leadership is the proven means of creating a safety climate in the organization, positively affecting employees’ perceptions of the workplace safety climate [
13,
25,
27,
48,
49,
50,
51].
The human being is regarded as a key factor in generating accidents on account of errors and slips in compliance with protocols, procedures, and OHS regulations. Finding possible methods to influence and determine a reduced rate of accidents caused by human errors is of high interest considering the significant number of fatal accidents still occurring worldwide. From this point of view, research on connections between safety climate and safe behaviour have the potential to answer the question of how to generate safe behaviours without using coercive measures against employees [
20,
59,
60,
61,
64]. A positive psychosocial climate leads to improved safety culture, enhancing safety performance [
85]. Therefore, transformational safety leadership should be harvested in organizations to encourage the development of a safety climate as part of the organizational culture. These results are very important considering the role played by employees’ safe behaviour in the reduction of work-related accidents.
As per the research performed in this study, all four hypotheses proved to be relevant, the proposed methodology being consistent with similar studies [
80]. The effectiveness of leadership, punctually measured within the concept of safety climate, can be consistently monitored, streamlined, and strengthened by transposing the results of the study within the concept of safety culture. This unitarily contains both managerial, as well as cultural and normative, influence factors. The holistic and integrated approach is possible through strategic policies concerning total safety management (TSM), Zero Accident vision, or total quality management (TQM). In the current epidemiological context, the approach must maintain a consistent strategic and synergistic balance between workplace safety and health binomial.
5.1. Theoretical and Practical Implications
The current research contributes to examining the relationship between safety leadership and safe behaviour. In the studies conducted on this subject, it is seen that the mediating effect of the safety climate in the effect of different types of safety leadership on safety performance indicators is examined based on different variables. For example, Wu et al. examined the mediating effect of safety climate on the effect of three-dimensional (safety coaching, safety caring, and safety controlling) leadership on safety performance [
28]. Zhao et al. focused on the effect of transformational leadership on safety participation, which is a dimension of safe behaviour [
62]. The current research contributes to the literature by focusing on transformational leadership on the one hand, and the safe behaviour of employees, including direct safety compliance, on the other. As a result, it is thought that the variables discussed in the research contribute to the theories to be developed in the field of occupational safety.
This research has practical implications for managers and experts working in the field of occupational safety, who are involved in the prevention of occupational accidents. Research findings show that it is important for managers and experts who want to increase the safe behaviour of employees to exhibit transformational safety leadership. Accordingly, transformational safety leadership will lead to a more positive perception of the safety climate by employees and ultimately to safer behaviours and lower work accidents. At this point, it is recommended that organizations pay attention to the employees that they will assign in the field of occupational safety to ensure suitability for a transformational leadership style. This research also has important implications for policymakers who work to prevent occupational accidents. The results of the research show that the leadership perceptions of the employees and the perceptions of the safety climate are important in promoting the safer behaviours of employees. Considering the human and economic losses caused by occupational accidents, it would be beneficial to consider this point in the studies carried out on a national scale to prevent occupational accidents.
5.2. Limitations
The present research had certain limitations referring to self-reporting, geographical, sectoral, and analysis constraints. The first limitation of the study is that the research data was collected based on the participants’ self-reports and perceptions. Therefore, some of the obtained data may contain bias due to the participants’ reluctance to report their true perceptions. In addition, the research was carried out with employees in the manufacturing sector, particularly employees operating in two manufacturing plants in an urban area in Turkey and Romania. Implementation of the research methodology in different cities/countries and sectors will reveal the different dimensions of the problem for a more general and comprehensive perspective on this matter. In addition, the mediation hypothesis—which is the subject of the analysis—was validated using the Preacher and Hayes plugin in the SPSS package program. It can be thought that the results may differ if alternative software solutions would be used (e.g., Lisrel, SmartPLS).
5.3. Future Research Directions
This research focuses on transformational safety leadership, safety climate, and safe behaviour. As stated in Manjula and De Silva’s research, many personal and organizational factors can be effective in the safe behaviour of employees [
86]. Examining the mediating effects of personal and organizational factors other than the safety climate in future research will make significant contributions to revealing all aspects of the subject [
87,
88,
89]. In this study, research hypotheses were tested on a sample that included only manufacturing workers. Future research on this subject in other sectors will contribute to the full disclosure of all aspects of the picture [
90].
