CRE& paperwork

I was fired recently from CRE. When my final check was posted they took everything I had made for their school payment . I expected a payment to come out as per agreement. When I called payroll about it I was told that was the agreement I signed. I asked for a copy to be sent to me. I was told it would be in the mail today. After that I contacted their personel dept. and asked for copies of everything I signed while in their employ. I was told nothing would be sent, it was strictly CRE's property, I can go to salt lake city & look thru it but it can't leave the property. Is there anything that can be done about this ?
