Examining the Impact of Ethical Leadership in Unions on Employee Pro-Organizational Behavior: A Study on the Relationship with Unethical Conduct

Unethical pro-organizational behavior (UPB) is a topic of significant interest in leadership research. This paper introduces trade union moral leadership as a novel antecedent variable of employee UPB and examines its moderating effect on the relationship between corporate moral leadership and employee UPB, based on the concept of "dual organizational moral situation-employee behavior." The study surveyed 211 enterprise trade union members and found that: one There is an inverted U-shaped relationship between corporate moral leadership and employee UPB, with trade union moral leadership having an additional inhibitory effect; two Trade union moral leadership has a negative buffering effect on the curve relationship between corporate moral leadership and employee UPB. As the level of trade union moral leadership increases, the negative impact of corporate moral leadership on UPB weakens; three Trade union moral leadership has a positive moderating effect on the curve relationship between corporate moral leadership and employee UPB. As the level of trade union moral leadership increases, the curve between corporate moral leadership and employee UPB reverses to a diminishing marginal trend. These findings not only contribute to research on factors that can inhibit UPB but also provide practical guidance for enterprises to improve moral leadership management and avoid moral hazard.
