My wife was fired recently without warning. She has filed for unemployment and had an initial interview with the unemployment office today. They claim that her former employer told them that she was “not doing her job” but I have never heard anything from her regarding performance issues. They also claimed that they “talked to her about her performance” and she claims that they never made any attempt to correct her performance and was unaware that they were unhappy with her.

What does this mean for her eligibility for unemployment? Is there any recourse?
