I was recently fired for misconduct which was legitimate. I filed for Unemployment, was denied, appealed the decision, had a hearing and lost that too. I am now going to file a 2nd appeal and must write a letter. Now, 3 other people in my same department committed the same exact misconduct w/in the last year or 2, during which time no company policies have changed. All three were confronted by the program director and admitted what they did, same as I did. All three were then given a warning which was documented in their files. I got no warning and was fired 2 hours later. There is no warning in my file to date. I don't know if I have a leg to stand on and if so, how do I include this into my letter? During my appeal hearing I was asked if I was warned and I said no. I started to give info about the others not being fired, I was told by the mediator that the hearing was about me, not other employees. Any tips?
