Denied unemployment, how do I appeal? - 25 weeks in

My claim was denied after 25 weeks of waiting, and the letter says I have a short window to appeal. Thank you in advance. 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 saved me later.

Legal aid offices and some workforce centres help with unemployment hearings at no cost. A call is worth it.
