I could have stayed in current position. I created the number that made it worthwhile.

I also made a couple of demands on free days which made sure certain days off matched my wife's schedule. I also chose which group of people I wanted to work with since this is 4 days one week and 3 days the next, and we are grouped on "platoons". That made my boss juggle the other guy in this position to the alternative days, essentially forcing him to switch to the other platoon.

I made the decision on what was worthwhile, and now it is time to live up to my side of the bargain.

I've been doing it a few days now without the evil guy, he's been on vacation, so at least I've gotten comfortable with the responsibilities without the pressure of him being there.

This job is pure multitasking. And I suck at that. So does everyone else, but at least I know it and have mitigation strategies. It's been fun.
