Denied unemployment, how do I appeal? - 5 weeks in

I got a denial letter last week saying I left my job voluntarily, but I was let go as a forklift operator. I do not usually post, so bear with me. My employer's version of events does not match mine, and I have emails that show 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.
