Hidden Human Capital Risks to Sustainable Logistics Systems: A Moderated Mediation Model of Overqualification, Abusive Supervision, and Workplace Ostracism
研究土耳其物流业员工发现，感觉大材小用会通过上司辱虐管理导致工作疏离，而同事排斥会加剧这一过程，对物流企业防范人力资本风险有参考价值。
ABSTRACT This study examines how perceived overqualification (POQ) becomes a source of work alienation by focusing on interpersonal dynamics in the workplace. Drawing on relational and power‐based perspectives, we propose that abusive supervision serves as a key mechanism linking POQ to work alienation, while workplace ostracism conditions the strength of this process. Using survey data from 320 full‐time employees in the Turkish logistics sector and structural equation modeling, the findings show that POQ is positively associated with abusive supervision and work alienation, with abusive supervision partially mediating this relationship. Moreover, workplace ostracism strengthens both the relationship between POQ and abusive supervision and the relationship between abusive supervision and work alienation. Taken together, these results indicate a moderated mediation process in which the indirect effect of perceived overqualification on work alienation via abusive supervision is contingent on levels of workplace ostracism. Overall, the study advances a relational understanding of overqualification by demonstrating how supervisory and peer‐level mistreatment jointly shape employees' experiences of alienation at work.
