Denied unemployment, how do I appeal? after 18 years as a recruiter

I was told my separation was for misconduct, which is not what happened. I have not done a hearing before and I am nervous. If you have appealed before, what helped you prepare?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.

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