Got a denial letter for unemployment, what now?

My claim was denied after 14 weeks of waiting, and the letter says I have a short window to appeal. 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.

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