The Impact of Physical Hazards on Workers’ Job Satisfaction in the Construction Industry: A Case Study of Korea

This study investigates the impact of workplace physical hazards on job satisfaction in the construction industry, focusing on the mediating role of mental threats and the moderating effects of perceived job quality and security. The study findings indicate that exposure to physical hazards significantly contributes to mental stress, leading to reduced job satisfaction. Importantly, a heightened awareness of physical risks amplifies the mental burden, further decreasing job satisfaction. Furthermore, the study highlights that perceived job quality and job security can buffer the negative effects of mental threats on job satisfaction, suggesting that enhancing these factors may alleviate some of the adverse impacts of physical hazards. This research provides important insights into the complex relationships between physical work conditions, psychological stress, and employee satisfaction. It emphasizes the need for construction companies to implement practices that not only reduce physical hazards but also improve perceived job quality and security to foster employee well-being. The study contributes to the literature on occupational health and safety, offering practical implications for managers and policymakers aiming to enhance job satisfaction and retention in physically demanding environments. Future research should explore the long-term effects of these relationships and how they may extend to other high-risk industries.
