This study sought to understand how the differences between rewards influence the perception of fairness at work and the motivation of civil servants and commissioners of the Court of Auditors of the State of Alagoas - TCE/AL. The research provides important insights for public managers into how motivation and reward equity can improve the performance and satisfaction of civil servants and commissioned staff. This is an exploratory, bibliographical and case study, and in terms of its nature it is classified as a qualitative study. It can therefore be said that there are differences between the rewards received by civil servants and commissioned staff at the Alagoas Court of Auditors, and this means that civil servants are aware of the value attributed to their work in relation to what is practised within the group, as well as the differences in rewards directly interfering in the motivation of civil servants and commissioned staff. However, this lack of motivation may, in many cases, be associated with a lack of opportunities for career progression, recognition and appreciation of their work by the managers in charge of the body.
