Performance appraisal is a management tool. As such, managers may use the power of the tool in various ways. For example, a manager may use overly positive performance ratings as a reward for someone who spearheaded a project for the manager. Likewise, a manager may use overly harsh ratings as punishment for someone who objected to a project the manager promoted. As a leader in an organization, what steps would you take to ensure that the performance appraisal system is fair to all employees? Substantiate your opinions by using outside sources.
