Towards A Better Understanding of Psychological Contract Fulfilment and Organisational Citizenship Behaviour (OCB

The social exchange theory holds that the relationships between psychological contract and OCB can be understood in terms of perceived contractual reciprocity and that employees are more inclined to respond positively to psychological contract fulfilment by taking on additional duties that go beyond their formal duty schedule. Therefore, this study examines the influence of psychological contract fulfilment on the performance of OCB in the Nigerian banking industry. A sample size of 402 bank employees was selected for this study, and data for this study were collected using a structured questionnaire. Findings from the study indicate that psychological contract fulfilment has a significant positive influence on the performance of OCB by employee in organisations and that the supportive employment relationship dimension of psychological contract fulfilment has more influence on the performance of OCB than the pay dimension.
