Abstract This study examined the relationship between employee age and performance, defined as in-role performance and organizational citizenship behaviors (OCB), using a sample of 599 hospitality employees from Hong Kong. Results of a regression analysis indicated a negative relationship between age and in-role and OCB. We also examined whether organizational commitment is a necessary condition for older workers to perform well. Findings indicated that organizational commitment moderated the relationship between age and work performance, such that the relationships were strong and negative only when commitment was low.
