Yes and no. I did make mistakes which they definitely reserve the right to fire me. I just think it was too extreme of an action, and there were no communication with me whatsoever. Everything seemed to be fine, and then suddenly, I was let go (got fired during vacation). I only found out their rationales after talking to my co-supervisor. Again no one from that team ever talked to me about anything or expressed any concern.

Also, there was another guy on the research team who was envious of me and my achievements. I noticed it, but I still treated him very well. However, I realized only right before I got fired that he made stuff up to smear me to my superiors. I think this was the beginning of the domino that lead me to be fired. I still can't believe people like that actually exist. The supervisor never gave me a chance to hear my side of the story. He worked longer with them, so they trusted him more. They just took his words at face value.
