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 payroll clerk. There are 7 people counting on me, so I am trying to be careful. My employer's version of events does not match mine, and I have emails that show it.

Thanks for writing this out. I went through something close to it 10 months ago, and it settled down once I kept a simple log of every call and form.
