Drawing upon the appraisal theories of emotion and literature on liking, this study explores the dual effects of leaders’ liking for followers on followers’ extra-role behaviors. Through a two-wave, multi-source survey in a field setting, the results revealed that leaders’ liking can promote followers’ organizational citizenship behavior and negatively impact their organizational deviance; under the joint effect of the followers’ perceived rarity of competence and Chinese traditionality, leaders’ liking can either promote followers’ organizational citizenship behavior by increasing their gratitude, or facilitate their organizational deviance by evoking their hubristic pride.
