I once got chewed out by a finance director because we in IT had scheduled updates (and their associated restarts) to run on weekends. This guy was in the habit of creating important financial spreadsheets and then never saving them, just leaving them open all the time. So he came in one Monday and found all his work gone.

There was a rumor that when he was let go, the police had to drag him from the building kicking and screaming. That rumor was not true, but it was plausible.
