Abstract

With the rapid development of Chinese high-speed railways, the phenomenon of "perceived overqualification" has begun to appear among high-speed railway operators in China. Relying on social cognition theory, we conducted a hierarchical regression and Bootstrap analysis with a moderated mediation model. Specifically, we proposed that perceived overqualification positively affects high-speed railway operators' safety participation via the role breadth self-efficacy. Further, this indirect effect is moderated by operators' perceived organizational support. Using matching data from 263 Chinese HSR operators and their leaders, we found that all hypotheses were supported. Our results showed that the level of operators' role breadth self-efficacy mediates and elaborately explains the relationship between perceived overqualification and safety participation. Moreover, the operators' perceived organizational support regarding safety is a catalytic factor that increases the positive effects of perceived overqualification. From a practical perspective, the results spark encouraging suggestions for the onboarding process, for intervention planning regarding operators' perceived overqualification, and for organizational socialization in safety-related enterprises.
