I live in California, and am currently finishing up my BA and credentials. School A offered me a position, and stated that it was a preliminary offer and I was interested and accepted. It had been a month and no one from the district contacted me. I did research about their benefits, pay scale, and school and wasn't happy with what I found. I went to the district office and the hr lady told me that she was going to be calling me in soon to sign all of the paper work and that it would take upwards of an hour. At that point I let her know I wanted to withdraw my application and decline the offer. She told me that the "Preliminary Offer" I signed was binding and that I was under contract with the school district and needed to write a letter to them (which needs to be approved by the superintendent). I am now extremely worried that I have done something wrong and made a huge mistake that will affect my career before it even starts. I don't understand how I can be under contract if I never signed a contract to begin with. Can this negatively effect me?
