Executive safety leadership is essential to prevent accidents in the workplace. However, will safety be secured by emphasizing only executive safety leadership to workers? In this study, the impact of executive safety leadership on the workplace hazard level was analyzed by adding the supervisor's safety role as a mediating variable. This paper shows that executive safety leadership has no direct effect on workplace hazard levels. However, executive safety leadership was found to have a significant impact on the supervisor safety role, and the supervisor safety role was found to lower the hazard levels in the workplace. In summary, executive safety leadership was found to reduce the hazard levels in the workplace through the full mediating effect of the supervisor safety role. Based on these research results, this study seeks to present the following recommendations to the government and management: The government should ensure that a workplace safety and health system is established by strengthening the effects of other mediating factors, such as strengthening the role of supervisors who are actually responsible for workplace safety and health. Executives must grant supervisors actual authority and responsibility to properly perform their safety roles and establish personnel and performance evaluation systems.

Background: This study examines whether employee perceptions of supervisor behavioral integrity for safety moderates the relationship between top-management safety climate and safety performance (i.e., safety compliance and safety participation) and the mediated relationships through safety motivation. Methods: Data collected from 389 blue-collar employees were analyzed using latent moderated structural equation modeling. Results: The results indicate that the relationship between top-management safety climate and safety behavior, and the mediating role of safety motivation were replicated. Moreover, the results show that the mediated relationships between top-management safety climate and safety behaviors through safety motivation were stronger for employees who report high supervisor behavioral integrity for safety. Conclusion: The study findings suggest the role of supervisor behavioral integrity for safety in clarifying how the employee perceptions of top-management safety climate transfer to the employee safety behaviors through the motivational pathway.

A supervisor's role is very important to have accident free environment in a company. In order to take full advantage of safety management system, company safety supervisors require to learn how much responsibility they have in their company. To improve safety supervisor's knowledge, they must spend time to learn the importance accident free environment. To improve the efficiency of safety management, the supervisors need to voluntarily emphasize the importance of safety management.

Background: Workers exposed to hazards without adequate protections are at greater risk of injury and illness. Supervisor activities have also been associated with injury risk. We examined the interplay between supervisor safety support and occupational health and safety (OHS) vulnerability on workplace injury and illness. Methods: A survey was administered to 2,390 workers employed for more than 15 hrs/week in workplaces with at least five employees who had a direct supervisor. We examined the combined effects of hazard exposure with inadequate protection (OHS vulnerability) and supervisor support on workplace injury and illness, using additive interactions in log-binomial regression models. Results: OHS vulnerability and lack of supervisor support independently increased the likelihood of physical injuries at work. Crude and adjusted models showed that the risk of physical injury was at least 3.5 times higher among those experiencing both OHS vulnerability and a lack of supervisor support than individuals without OHS vulnerability and with a supportive direct supervisor. Workers who experienced vulnerability were at less risk if they had a supervisor who was supportive. Conclusion: In workplaces where workers experience one or more types of OHS vulnerability, having a supportive supervisor may play an important role in reducing the risk of injury and protecting workers.

This research examines the causal relationships between supervisor trust and organizational citizenship behavior(OCB) and the mediating role of organizational trust on OCB. Using the sample of 282 small and medium sized enterprises' employees, this study analyzes three alternative hypotheses centered around supervisor trust, organizational trust, and OCB. The results show that supervisor trust has a strong positive effect on OCB. Second, organizational trust is positively related to OCB. Third, this research proves that partial mediating effects of organizational trust exist between supervisor trust(relational trust) and OCB(civic virtue, sportsmanship). Finally, this research proves that a full mediating effect of organizational trust exists between supervisor trust(calculative trust) and OCB(sportsmanship). This study recommends supervisor trust, organizational trust be valued in order to increase OCB vital for organizational effectiveness or productivity in small-medium sized manufacturing enterprises.

Domestic plant construction sites have a tendency to become bigger, more various and complicated. Moreover frequency of industrial incident is increasing due to short project period, coexistence work condition and using heavy construction equipment. Installing safety facilities and safety training contribute to prevent incident. But mostly incident happens due to workers' unsafe action and wrong work method. Technically, it is very difficult for us to closely manage workers preventing incident. Therefore, the role of foreman who ordinarily works together with his workers is considered more important. Specific execution plan was drawn through industrial incident statistics from Ministry of Labor and questionnaire survey to interest parties(supervisor, safety staff and foreman). If foreman has raised sense of belonging and responsibility by conducting practical safety training for his workers, manages job site and receives proper compensation for these roles, it will be expected that it fully influences incident decrease.

Objectives: The purpose of this study is to identify the general characteristics of manufacturing workplaces and the characteristics of safety and health organizations, and to determine the impact of safety and health-related communication within these organizations mediated by supervisory safety and health management personnel. Methods: This study is based on the Korea Occupational Safety and Health Agency's 2018 Occupational Safety and Health data targeting 1,486 manufacturing sites. Data were analyzed using descriptive statistics, t-test and ANOVA, and mediator variable regression analysis using SPSS 25.0. Results: The average score on communication levels related to safety and health was 11.20 out of 15. The average score of the safety and health management level was 31.04 out of 40. As a result of mediation regression analysis, it was found that safety and health-related communication had an effect on the safety and health management level (𝛽=0.434), and the number of safety and health supervisors was found to mediate the effect of this variable (𝛽=0.069). Conclusions: The level of safety and health-related communication affects the level of health and safety management, and the number of supervisors mediates this influence. Therefore, the role of the supervisor is important in safety and health communication. It is expected that the level of safety and health management can be improved through management and supervisors.

This study attempted to provide implications by analyzing the impact of business Owner's safety commitment on industrial accidents and examining the mediating role of management supervisors' safety leadership and worker participation. Analysis was conducted on 2,067 manufacturing sites with 20 to 50 employees in the 10th Occupational Safety and Health Survey data. SPSS waw used to secure the reliability of the measurement variable. Hypothesis vertification was carried out after securing the suitability and validity of the structural model using AMOS. The direct impact of three latent variables on industrial accidents was confirmed: the business owner's safety commitment, the management supervisor's safety leadership, and the worker participation. The employer's safety will and the management supervisor's safety leadership do not directly affect industial accidents, but it has been verified that worker participation has a diret impact on industrial accident reduction. In addition, it has been confirmed that the safety leadership and worker participation of the management. Supervior have a complete mediating effect on the reduction of industrial accidents by mediating with the safety leadership of the management supervior and the participation of the workers. This study analyzed the impact on industrial accidents by dividing the stakeholders constituting the workplace into three classes: business owners, superviors, and workers, but the results suggest that employers and all workers inside the workplace may be organically linked to achieving the goal of reducing industrial accidents. Therefore, in order to establish an autonomous safety management system for safety and health at workerplaces, efforts are needed to reduce industrial accidents in their respective location by forming an organic community among internal stakeholders.
