The biggest reason to knock off working on vacation or after hours is that it creates a false expectation on the the workload. If you can’t get it done during regular office hours, than that means your company needs more people or a process improvement.
If you are working these extra untracked hours, you are the problem. If you get rewarded for doing so, your company is toxic and will only expect more as you move up the ladder.
No one on there deathbed will say they wish they worked harder. They will regret all the other moments they missed because they were working too much.
Time is more than just money, it’s your life.
