A Study on the Factors Affecting Safety Behaviors and Safety Performance in the Manufacturing Sector: Job Demands-Resources Approach

(1) Background: The dynamic nature of workplaces highlights the urgent need for effective strategies to promote a safe working environment and enhance workers’ well-being. These strategies must address both organizational safety performance and individual safety behaviors. (2) Methods: This study employed the job demands-resources (JD-R) model to examine the impact of workplace factors on safety behaviors and organizational safety performance among 3255 manufacturing companies. The data utilized in this study originate from the 10th Occupational Safety and Health Status Survey by the Korea Occupational Safety and Health Research Institute (KOSHA). (3) Results: Occupational stressors involving physical and psychological risks (job demand) significantly reduced employees’ adherence to safety practices while increasing workplace diseases and accidents. Conversely, when job resources were effectively mobilized to bolster individual resources, safety behaviors improved, and the incidence of workplace diseases and accidents decreased. Middle managers’ safety competency emerged as a critical moderating factor in these relationships, amplifying the positive impact of job resources. (4) Conclusions: The results highlight the necessity of managing physical and emotional hazards while enhancing middle managers’ abilities to promote workplace safety. A multidimensional approach is essential for preventing workplace accidents and improving safety outcomes. Implementing a comprehensive stress management system is particularly vital to safeguarding workers in the manufacturing industry.
