I was employed by a sports management company on a part time basis with a contract from March 2025-August 31st 2025. I received emails in august asking if we were returning for the fall and what types of shifts we wanted, I had also corresponded with my supervisor about new programs coming up that i could partake in. After one shift on the what I assumed was a Tacit renewal of my contract, I was informed that i was being not renewed as of September 1st and the shifts i was scheduled for after that date were a mistake. They said it was due to unacceptable behavior so i asked for clarification on what i had done and they said that "it was said that you called others stupid for doing things a certain way, i hadnt done what the coordinator had asked one time, it had been heard that I had said i dont "need" the job because I have a full time job, and finally because at some instances they felt my face didnt look like i wanted to be there". Is this allowed? a retroactive non-renewal feels sketchy and on top of that, their reasons have a discriminatory lean to it. Just want to know if they did anything legally wrong that i could write them a letter about.
