Well, I tell you what I'm going to do: I'm going to find me a 1st shift job, that's what.
In the meantime, it appears that I'm not being fired and that they are willing to work with me to make the time I have to spend here as painless as possible. So I'm going to ponder schedule shifts for a bit and come up with a proposal. Suggestions welcome, with the caveat that I am, for the time being, still stuck with 3rd shift.
