The performance appraisal process is increasingly seen as a key link between employee behaviour and an organization’s strategic objectives. Unfortunately, performance reviews often fail to change how people work, and dissatisfaction with the appraisal process has been associated with general job dissatisfaction, lower organizational commitment, and increased intentions to quit. Recent research has identified a number of factors related to reactions to performance appraisals in general and appraisal satisfaction in particular. Beyond the appraisal outcome itself, researchers have found that appraisal (...) reactions are affected by perceptions of fairness and the relationship between the supervisor and the employee. To explain the relationships among these factors, the present article proposes a moral cognition perspective. We suggest that employees judge a performance appraisal from the perspective of its moral justifiability, and that appraisal reactions will be determined, at least in part, by the perceived moral justifiability of the process. The proposal was supported by results from a survey of government employees using measures of performance ratings, leader–member exchange, perceived utility, and organizational justice. (shrink)
