Drawing on ego depletion theory, this study aims to provide insights into the effect of work-family conflict on the high-speed railway (HSR) drivers’ safety performance by examining the mediating role of ego depletion and the moderating roles of work-family centrality and supervisor safety support.
In total, 243 HSR drivers from 7 railway bureaus in China were surveyed. Structural equation modeling was used to test the hypotheses.
Both work-to-family conflict and family-to-work conflict have direct and positive effects on HSR drivers’ ego depletion and indirect effects on both safety compliance and safety participation via ego depletion. Moreover, both the direct effect of work-family conflict on ego depletion and its indirect effect on safety performance are moderated by work-family centrality. Supervisor safety support plays a buffering role in the relationship between ego depletion and safety performance.
This study examined the relationship between work-family conflict and safety performance based on the perspective of ego depletion theory. The findings testify to the importance of reducing work-family conflict among HSR drivers pursuant to maximizing safety.
