One day boss comes in and sees my colleague. Remarks how early he came in. He said he never left the previous day and planned to just keep working (salaried guy). Boss said he needed to take the day off, wouldn’t have him drive, and he drove his car and had me follow to take the boss back to work after dropping colleague and his car at home.

He consistently tried to break that guy’s incessant overworking. Had a lot of respect for him.

Unfortunately he got canned when he kept some stuff from upper management in writing that got upper management in trouble. Not enough trouble to remove their ability to retaliate, but enough to save a few other jobs of folks they were trying to throw under the bus for their mistake.
