In recent years, the adverse implications of organizational identification (OID) have received significant attention in the field of organizational behavior research, particularly as it is considered a critical factor in unethical pro-organizational behavior (UPB). Nevertheless, the findings of previous studies are inconsistent. To explain these discrepancies, we performed a meta-analysis of 54 independent studies from January 2010 to April 2023, comprising a total of 14,836 samples, to investigate the impact of OID on UPB and the moderating effects of cultural context. (...) The results of our study demonstrated that individualism, power distance, masculinity, uncertainty avoidance, and indulgence play moderating roles in the OID – UPB relationship. This study makes noteworthy theoretical and practical contributions and lays the foundation for future research. (shrink)
