You Don't Wanna Work For Fun

Jack retired years ago, and he has a mountain of money from several successful real estate ventures. Jack now works for General Standard Company for fun. He works to get out of the house and to feel young and important. He doesn't need the money, but still we heard that he haggled for a higher salary and consistently negotiates better raises. We hate Jack and see him as a drain on the company's resources. Also, has it been mentioned that he's annoying?
