Answer:
Jason's performance appraisal may be unfair due to likeability.
Step-by-step explanation:
The criteria that influence Jason's evaluation are not only his accomplishments. His low rates are based on the sympathy others feel or don't feel for him, which obviously doesn't affect his productivity, effectiveness or doesn't prevent him from completing his tasks successfully. It is an unfair performance review because it is based on how the others feel about Jason and it puts aside his goals.
