Appeal deadline questions after an unemployment denial - first time posting

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. 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.

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.
