I am a resident assistant at a public university in PA. I have been an RA for the past year, and have performed well. This year, during the rehiring process I was promised a position by my supervisor, who has the power to hire RA's. My supervisor told me in various meetings, emails, and texts that I was guaranteed a position for the following school year. I signed a routine University contract, indicating that I was not guaranteed a position next year, however my supervisor guaranteed me before and after signing this contract that I would absolutely have a position. Now, as the year ends he has just met with me and informed me that unfortunately there isn't any space for me. Even though I signed the University contract, do his guarantees of employment to me take precedent?
