The first thing you should do is hire an attorney who handles these types of appeals. Unemployment appeals can be very technical and there are rules of evidence that apply and if you don't know them then you can't make the proper objections. That being said, the question is did you quit? If you quit, then you will have to convince the referee that this wasn't a voluntary self-termination but rather there was a hostile work environment and you were forced out. People choosing to be unemployed won't get unemployment benefits, so you want to prove that this wasn't your choice but the will of the employer.
This is not to be considered legal advice nor does an attorney-client relationship exist.
When you quit, it is certainly more difficult to obtain unemployment benefits, but it is possible that you could convince unemployment to pay benefits here.
