Next Monday what I said was roughly this: "We've got more important tasks than the backlog now, let's discuss how we can fit them in later today". What I heard next were profanities saying that I literally fucked up and I have to do them after work.
(Mind you, this was not 1-on-1 but a team meeting, so the entire team was present, 3 more people) Next I asked whether I would be paid for that work and the answer, of course, surprised nobody. I asked him whether HR would share his point of view (This is a company who cares about the image of a model employer), to which he said that I come to work later than the hours that are in my employment contract. (This was a guy who supposedly cared about the output, not asses in chairs and he was OK with people showing up later) I grew tired of this attitude and politely told him that I already made arrangements for my next job and I quit.
Transferring my work to the team was smooth and I left in good spirits.
I'm sorry, but I don't see how this relates to the parent. Your story portrays a hypocritical and abusive manager. That "rule" was not enforced by the contract, and you were not legally obliged to follow it. I would've been more curious to see what you tried to do or say to repel it.
