This is a contribution to both practitioners and scholars interested in the human resources management and industrial psychology discipline. It presents a new dimension on commitment the employees have to their organizations, particularly, the public sector organization employees in Africa. Undertaking organizational commitment study, researchers often find themselves confronted with diverse questions which have to be blended together in order to understand and disentangle perceptions on why staff morale decline in many organizations. Initial studies have pointed out to a large role played by extrinsic rewards to the decline in staff morale. The current research stretches the scope of study to find the impact of both the extrinsic rewards, intrinsic rewards as well as the social rewards on enhancing organizational commitment of employees in the public sector organizations, reference herein being made to the government ministries. The author believes this study will open up for more academic debates and invoke new arguments made in many studies of behavioural theories as propagated by academicians and writers in the human resource management and industrial psychology discipline
