I've resigned over unrealistic expectations from leadership about deadlines, and what was to be asked of my team to complete said deadlines. I would do it again. I'm sure I've had many many many failings as a manager, but I will not death-march any team under me with zero chance of success. There are several others in the GP's post. You are correct, they don't all apply and many may be harmful in a corporate environment, but that's why you get paid to separate the wheat from the chaff, right? :)
This sets great example. Thank you.
The team was not asked to pull any overtime to complete it in the proposed time frame.
I took a 6 month sabbatical and then was asked to contract for them remotely as a developer (instead of manager) which I did for several years after that.
So, wins all around, I suppose.
