Got a denial letter for unemployment, what now?, call-centre agent here

I was told my separation was for misconduct, which is not what happened. It has been weighing on me all week. The letter lists a deadline and a hearing process, but it is hard to follow. If you have appealed before, what helped you prepare?

File the appeal before the deadline, even if you are unsure. You can gather documents afterwards. That is the one part I would not wait on.
