Appeal deadline questions after an unemployment denial - what worked for you?

I was told my separation was for misconduct, which is not what happened. My employer's version of events does not match mine, and I have emails that show it.

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

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.
