The present study explored the issue of organizational citizenship behaviour (OCB) as a context-related phenomenon, from a multidimensional perspective. More specifically, it was hypothesized that organizational learning (structures and learning values) would be positively related to (a) OCB that benefited the organization as a whole (OCBO) and (b) OCB that immediately benefited particular individuals (OCBI). The hypotheses identified the school as the unit of analysis; so all variables were aggregates of individual responses to the organizational level of analysis. Justification for aggregation was provided by a within-group similarity index (rwg) and a within- and between-entities analysis (WABA). Results from a sample of 31 schools confirmed the main hypotheses, and generally supported the notion that OCB could be treated as a context-related phenomenon. These results should encourage researchers and practitioners to focus more attention on the organizational context and its characteristics as related to OCB.
