Appeal deadline questions after an unemployment denial after 15 years as a welding apprentice

I was told my separation was for misconduct, which is not what happened. This is my first time dealing with any of this. The letter lists a deadline and a hearing process, but it is hard to follow. Did you bring documents or only talk?

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

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