Abstract: The ethical climate of an organization is a crucial component of its environment, affecting its operational efficiency and prospects. This study utilizes the “job demand-resource” framework to construct a dual-path moderated mediation model of feeling trusted from supervisor’ influence on unethical pro-organizational behavior. The model is verified through hierarchical regression and structural equation modeling. The results indicate that feeling trusted from supervisor has a positive impact on employees’ unethical pro-organizational behavior. Role overload and perceived insider status play mediating roles between feeling trusted from supervisor and unethical pro-organizational behavior, and there is no significant difference between the two mediating paths. In-group social status negatively moderates the mediating effect of role overload on the feeling trusted from supervisor and unethical pro-organizational behavior, and positively moderates the mediating effect of perceived insider status on the feeling trusted from supervisor and unethical pro-organizational behavior. Organizations can effectively reduce unethical pro-organizational behavior by strengthening ethical awareness, paying attention to group influence and improving trust management, thereby enhancing overall organizational efficiency.
