I work in a school as a TA. I'm fairly new to the job. I come in at lunch, have lunch in the staff room along with other members of staff and start work afterwards.
Today I was having lunch along with one of the other TAs who works with me. Her hours are the same as mine and our roles are identical. We both had to be at the same place at the same time immediately after lunch.
I finished my meal and stood up to leave and take my plate to the dirty pile and she handed me her dirty plate and asked me to take it to the dirty pile for her.
Now, AIBU to think this was odd. I would never ask a colleague to clear up my dirty dish unless there was some pressing thing that I really had to get to right there and then (e.g. if a pupil got hurt and needed immediate assistance).
I was so surprised that I did it but she made me feel like her skivvy.
AIBU to think she was out of order?
