Denied unemployment, how do I appeal?, quality inspector here

My claim was denied after 16 weeks of waiting, and the letter says I have a short window to appeal. There are 12 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. Did you bring documents or only talk?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
