The current study presents an integrative model examining the double-edged sword effect of unethical pro-organizational behavior (UPB) from the perspective of the actors. Drawing on the moral self-regulation perspective and psychological entitlement literature, we propose that employees who engage in UPB may experience an increase in moral deficits and psychological entitlement, resulting in increased organizational citizenship behavior (OCB) and decreased work effort, respectively. We further propose that moral attentiveness strengthens the positive relationship between UPB and moral deficits but weakens the (...) positive relationship between UPB and psychological entitlement. Moreover, the strength of the indirect effects of employee UPB on OCB and work effort is also contingent upon employees’ moral attentiveness. The hypothesized moderated mediation model is supported by a multisource and time-lagged research design based on a sample of 256 supervisor–subordinate dyads. Key theoretical and practical implications and future research directions are discussed. (shrink)
