Office Space(1999)

Peter Gibbons is an office drone like many others, and he hates his routine life. One day, the occupational therapist who was hypnotising him keels over dead, leaving him with a permanantly altered attitude. Asked to come in on weekends, he responds by coming in only when he wants to, playing games on his computer and moving furniture to give himself a better view. But instead of firing him, the company takes this oddness as evidence of his managerial potential.
