So I signed up to be a tutor for a class under the understanding I would be getting paid for the position, though the prof did say there was a possibility funding would be cut. I assumed this meant that I would tutor for free. However, now that the semester has begun, it appears that not only will I not be getting paid, but I have to pay for the tutoring credits I'm signed up for. I've emailed my prof twice and she has not responded, so I'm kind of irritated. She said she would write me a fantastic LoR if I tutored for her whether I got paid or not, but I still feel like I'm getting jacked around. Am I right to be a bit pissed off about this?
