Performance appraisals play a critical role in an employee’s work experience. But considering that appraisals are performed by supervisors who might have ulterior motives, it is worth exploring how these motives affect performance appraisals.

THE RESEARCH ARTICLE

The motives addressed in the current article (Wang et al., 2010) include harmony, fairness, and motivating goals, all of which affect an employee’s performance ratings irrespective of actual performance. The harmony goal states that managers will inflate ratings of low performers to prevent conflict in the workplace. The fairness goal states that performance ratings will be lowered for high performers and raised for low performers when employees being rated are in the same work group or at the same job grade. The motivating goal states that managers will deflate ratings for high performers to motivate them to work harder and managers will inflate ratings for low performers to motivate them to work harder due to the disparity between actual performance and the performance rating.

The study suggests performance appraisals are not only impacted by actual performance. Instead, underlying motives of the rater or manager also impact the appraisal. Raters asked to focus on a specific rating goal disregarded the previous goal the rater had in mind.

THE BOTTOM LINE

The results of the article suggest that prior to the performance appraisal process, managers must receive training regarding possible ulterior motives. Companies must factor in these underlying motives when considering performance appraisal results.
