Input: Some background: I didn’t choose to be his TA in the first place, but my counselor put me into his class. I’ve never had him as a teacher before, and we hardly ever talked while I was his TA. We’re not friends, and I would go so far as to say we don’t even really have a strong working relationship. 

But next semester I’m gonna be TAing for the teacher across the hall, and I’m not sure if I should talk to my current teacher about it or not.

Honestly, it makes no difference to me either way, and based on his general attitude I don’t think it makes much of a difference for him either, especially because there will still be another TA in that class. He didn’t make us TAs do a whole lot, and he probably won’t even notice that I’m gone.

So I wasn’t planning on telling him

Would I be the asshole?

not telling my teacher that I'm not going to be his TA next semester
