When Character Peter Gibbons (main character) comes into the "office" to have his meeting with the Bills (the two people the company Initech hires to fire people) a chair is pushed out on the side of the table Peter sits at. Then it goes to a new shot (one from the Bills point of view) as Peter gets a glass of water. When the shot comes back to the first angle the chair is pushed in. I dont think the Bills did it....
