The relationship between dimensions of individual level culture-related variables (social axioms) and the categorization of organizational citizenship behaviours (OCB) as in-role versus extra-role was explored within a Canadian sample. In order to appropriately address levels-of-analysis issues, this study focused on the relationship between two variables at the same level of analysis: individual social beliefs and individual perceptions of what constitutes OCB. Results indicate that the extent to which each of the OCB dimensions were viewed as in-role versus extra-role varied considerably among participants and that this variation could in part be predicted by social beliefs. The implications of understanding culture\u27s effect on employee work behaviours and attitudes are discussed
