I was recently terminated for not signing a contract with my work. I work for a private school and was asked to sign a contract for the 2010-201l the pay was only 13,775 dollars for the year. I told her I had to keep my options open, as this was not enough pay. Then she fired me. I have a bachelor's degree and and have a professional certification to teach. I don't understand how she can get away with paying her employees this. Is she allowed to do this? Can she fire me for not signing?
As a general principle, at-will employees of a private employer can be terminated for any reason or no reason at all, unlawful discrimination excepted. There are a small number of other reasons as well. You do not mention a current contract, so I assume you don't have a current contract. Similarly you don't mention a union, so I assume you're not a union member.
If you reject the contract offered to you, I see no reason why you can't be terminated, according to general principles of law. Your remedy is to find a better job that pays more. If she can find another teacher who'll accept the contract terms, then the salary in the contract is "what the market will bear."
