<prompt> Human: Last month I was recruited to work for an educational organization due to my experience in my field. I accepted the job and signed a 1 year contract that was based on my years of experience. The pay scale and benefit package are negotiated through union collective bargaining. I began work 4 weeks ago and its been going good. Today, I got a call from my HR hiring manager and was told they made a mistake on my pay scale and contract. HR says according to the labor agreement a new employee with a 1 year contract can not exceed step 10 on the pay scale. I was hired and signed my contract as a step 13. This is about a 10 difference in pay. HR says they need to reduce my pay to comply with the labor agreement. Any thoughts... I am pondering all options.  <response>: It sounds like theyve signed two contracts which are in disagreement: they signed one with you, and they signed allegedly another one with some union. You presumably were not party to the union contract not sure about this; are you a union member?, but you were certainly a party to the contract between you and the employer.Basically, this sounds like a lawsuit to me: they cant change your salary unilaterally, because thats a breach of their contract with you, and you can sue. If they fire you because you wont agree to an amendment, that sounds like grounds for an improper termination lawsuit. Their best option is to shut up and hope the union doesnt find out, but if they do, thats really not your problem.My advice: 1 get a lawyer, 2 do NOT sign ANYTHING until talking to a lawyer, and 3 start looking for a new job.
