Purpose: This study seeks to examine the impact of career growth prospect (CGP) and formal mentoring support (FMS) on overall organisational citizenship behaviour (OCB) and its five dimensions. Design/methodology/approach: Data were obtained from 72 supervisors and 182 of their subordinates in branches of a bank located in a city in South-western Nigeria. Findings: Results indicate that CGP accounted for a significant percentage of the variance in overall OCB (β=0.46, p<0.001), predicting three dimensions: sportsmanship, conscientiousness and civic virtue. Contrary to hypothesis, FMS did not predict overall OCB, but significantly influenced three OCB dimensions: sportsmanship, courtesy and altruism, predicting "sportsmanship" (β=0.26, p<0.001) to be better than CGP (β=0.22, p<0.01). Research limitations/implications: Although generalisation is limited in a study of a single organisation, the findings of the study imply that CGP and FMS have differential relevance in OCB. Practical implications: Altering negative perceptions of CGP among employees engenders OCB but FMS needs to be complemented with other interventions to foster overall OCB. Originality/value: Although career growth prospects and formal mentoring support are projected to foster OCB in the Nigerian banking sector, no research has investigated this expectation. The extant literature shows that research on the impact of career growth prospects on OCB is virtually absent. Again, the absence of African perspectives on research issues such as OCB, has limited comparative studies and the global scope of most reference journals. This study narrows these gaps in literature and contributes empirical information that equips management to deal more strategically with the integrated approach to OCB. © Emerald Group Publishing Limited.
