Explanation:
The performance appraisal is a routine analysis of the results of an individual and of a company's total commitment. A performance appraisal, also defined as an «yearly review», "performance review," or "individual appraisal," assesses the ability, success and progress of an employee or its lack of it.
The manager who is neither tough nor easy with rating employees is committed to negative and positive leniency misconceptions. In the performance evaluation process, the employee's unjustified expectations for increases, promotions or tough jobs can be increased by positive leniency.
The worker may be sick of hitting the head against a wall with excessive slowness or toughness/strictness because the manager can not be pleased despite how hard the person tries.
