A coworker years ago got called into the office to receive a hour-long cursing-out by his manager and his manager's manager. Several times during that hour, he tried explaining the situation that it wasn't his fault, nor his team that had caused the problem. It was a competitor that made a huge mistake and the company was nowhere near the area (think counties away). Both of the bosses didn't like that answer and kept reaming him out.
Immediately after the meeting, he walked into his office and drafted his retirement paperwork and sent it to HR. The company was so large, he was able to get the paperwork through without his boss knowing. The retirement package was completed and on his last day, he walked out the door after taping a note to his monitor. All it said was “Here's the keys, here's the passwords. I'm retired, don't call me.”
Work called and called for weeks asking about projects until he changed his voicemail to that reply.
