A general term for the day-to-day dealings working in the office of a corporation... Pointy-haired bosses, meetings, cubicles, smelly coffee rooms, passing memos around, avoiding the boss when 5PM rolls around so you can leave without being told to stay late, etc.

Corporate culture differs with each company, of course, but you'd think from what people say that it is an evil thing at most offices. Dilbert is a good comic strip that describes corporate culture to a tee. So is the movie Office Space.
