Wrongful Termination?

My mother, who worked as a housekeeper for HealthCare Services, recently got terminated for not signing a contract with her employer. My mother, who only has an 8th grade education asked her employer to give a couple of days to understand what she was signing. All 8 employees working in her section asked for the same. Two days later, she signed the paperwork. She was the 2nd person to sign the paperwork, out of the 8 employees. All others signed later. My mother and another employee got terminated a few days days for refusal to sign, while the remaining 6 were unaffected.

She got denied unemployement benefits and is barely surviving. Does she have any legal protection? Anyway to get her unemployment benefits while she looks for another job?
