When employees identify with the groups and organizations they work for, this typically has positive implications for work-related attitudes and behaviors. The present paper provides a focused overview of the social identity approach to leadership and some ideas on its cross-cultural generalizability. To this end, we will first outline the basic tenets of the social identity approach and summarize the relations of organizational identification with work-related variables. Then, we will discuss the role of social identity-related concepts for effective leadership. In particular, we will present empirical studies on the following three aspects: (1) the transfer of leader identification onto their followers, (2) the role of leader prototypicality, and (3) the ways for leaders to actively manage the identities of the groups they lead. Finally, we will provide some suggestions on how to implement the principles of identity management into practice and offer suggestions for future research, with a special focus on China.
