Resolved

Big sigh of relief.

My husband spoke with his HR department AND his bosses boss and has been assured that if he has to miss his training class there will be no repercussions or problems. In fact, they're going to order him the training materials ahead of time so he can self study (which actually would work better for him what with his ADD tendencies).

We're both tremendously relieved.

Additionally, he's been given the OK to work from home for a bit after the baby is born so no more fretting about him only getting to spend a short bit of time with the tiny one when she comes home with us.

And his douchebag manager was called into a meeting with both HR and the big boss guy. Woot!
