Ugh, been there, done that. Teachers don't like to have difficult conversations or be truthful. I hated this. I'm like you and it rankled quite a few of my colleagues.
Being a therapist allows me to have as much or as little interaction with colleagues as I desire. My boss sees me as a team player, but I think it's because I do my paperwork in a timely manner. Others complain and I say it's nothing compared to what teachers do. Then I finish with, "I don't mind it because I am used to assessing 60-100 writing pieces every 10 days or so."
