This study aimed to examine the influence of age, tenure and education on organizational commitment in a developing country context. Focusing on Nigeria's dynamic banking sector, participants' age, tenure and level of education were measured against the three components of organizational commitment -affective, continuance and normative -in selected commercial banks to determine their relationship. The sample consisted of 303 full-time managerial and non-managerial employees from eight commercial banks located in the South-Western part of Nigeria. The study concludes that older, longer-tenured and more highly educated employees did not report a higher level of commitment than their younger, shorter-tenured and less educated counterparts with regard to affective, continuance and normative commitment. The practical implications of this result and direction for future research with regards to developing countries are discussed.
