So, I still have a job! Hooray!
My boss agreed to let me work between 10-15 hours a week and to choose the days and times that I will do that work (whether that be mornings or afternoons, every day or two to three days a week), plus the ability to do some work from campus or home. And the taking off multiple weeks for Christmas is no problem. Really, I couldn't have asked for a much better situation. I feel very grateful.
So. . . .um, that's it.
