The Ghanaian public sector has been plagued with a lot of productivity issues over the years. This has led to some think tank organizations in Ghana calling on public sector employees to be effective and efficient due to the critical role they play in economic development. These calls were climaxed by the president of Ghana in His Independence Day speech on March 6, 2017 where He challenged public sector employees to eschew laziness and work for the development of Ghana. As a result, this article describes a quantitative study that was conducted to examine the relationship between organizational commitment and organizational citizenship behaviours as these citizenship behaviours of employees can lead to improved organizational performance. Recommendations that will help improve upon the services of the public sector were provided in this article.
