<![CDATA[Safety and performance of train drivers are crucial factors in railway operations. Shift work systems involving night shifts, irregular rotations, and long working hours can lead to work-related fatigue (burnout), which impacts performance. This study aims to analyze the effect of work shifts on train driver performance with burnout as a mediating variable at PT Kereta Api Indonesia (Persero). The research uses a quantitative approach with a survey of 2,184 train drivers. Data analysis is conducted using Partial Least Squares–Structural Equation Modeling (PLS-SEM). The results reveal that work shifts have a significant positive effect on burnout (β = 0.608), work shifts have a significant negative effect on train driver performance (β = –0.339), and burnout has a very strong negative effect on performance (β = –0.839). Burnout significantly mediates the relationship between work shifts and performance, with a mediation effect of 51%. These findings emphasize that the decline in train driver performance is more influenced by burnout than by direct effects of work shifts. Comparatively, Japan’s fatigue management practices through a Fatigue Risk Management System (FRMS) are more systematic and preventive compared to Indonesia. This research contributes to strengthening the role of burnout as a mediating variable in the Job Demands–Resources framework and offers practical implications for PT KAI in reforming shift work policies for safety.]]>
