Identity and the extra mile: Relationships between organizational identification and organizational citizenship behaviour

The current study investigates the relationship between Organizational Identification and Organizational Citizenship Behaviour (e.g. helping colleagues, making innovative suggestions). We replicate earlier findings of such a relationship between those behaviours and organizational identification using ten samples across different occupational groups and countries in Study 1. Study 2 investigates the relationship in a longitudinal approach. Study 3 looks into this relationship on a group-level analysis while Study 4 extends our findings by linking identification to customer perceptions and financial performance, mediated by OCBs (Organizational Citizenship Behaviours).
