Nah dog, PTO is Personal Time Off. My time.

Don’t call me. Don’t email me. I might as well be dead to you. I got the slip signed and approved, and you all knew I’d be off - find someone else to deal with your problems.

If they can’t manage without you after all that advanced notice, that’s on them. And if the problem wasn’t actually critical and I can take care of it when I get back, well now it wasn’t so critical to solve right then now was it?
