The National Revenue Authority (NRA) of Sierra Leone has implemented employee work performance appraisals to enhance employee motivation and organizational performance. However, little research has been conducted to determine the effectiveness of these performance appraisals. Consequently, the purpose of this study was to establish the impact of fairness of manager’s recent appraisal, completeness of the appraisal and the extent of evaluation feedback of the appraisal system on employee motivation and the overall organizational performance.
