Denied unemployment, how do I appeal? after 17 years as a procurement assistant

I was told my separation was for misconduct, which is not what happened. I am in Tampa, in case local advice matters. My employer's version of events does not match mine, and I have emails that show it. If you have appealed before, what helped you prepare?

I printed my emails in order and wrote a one-page timeline. The hearing officer kept going back to it.

Stay calm and stick to facts. Mine lasted about thirty minutes and felt more like a conversation than a trial.
