SummaryThis paper examines how perceptions of Organizational Citizenship Behaviors (OCBs) are affected by socially constructed gender roles. We argue that gender roles are important for the perception, categorization, and consequences of OCBs. We suggest that the dimensions of OCBs (altruism, courtesy, sportsmanship, and civic virtue) are related to gender stereotypes. Combining social identity theory with gender role theory suggests that the`gender' of these behaviors, the job, the job incumbent, and the gender identity of the observer interact, potentially broaden the breadth of requisite job behaviors de®ned as either in-or extra-role. Implications are discussed.
