I got my boss's job by forwarding his private messages to HR. He sends me Christmas cards.

He had been quietly shifting client money into a personal account for months and it was in a group chat he thought was private. I did not hack anything. He added me by mistake. I forwarded it on a Friday, he was gone by Wednesday, and I was in his office by the following Monday. The company thanked me for vigilance. He sent a card last December, with a handwritten no hard feelings.
