[New Jersey] Preparing for an appeal hearing

Hi!

I was fired for from my barista job in November. I was fired because I “wasn’t nice to customers.” One of my coworkers told me that the owner (this is a small business) was telling people that I had been rude to his wife (idk who she is). Prior to this I had never been spoken to about an insubordination or failure to meet expectations. I applied for unemployment and it was denied as my employer cited “misconduct” as the reason for my firing. I appealed and I have my hearing tomorrow, but I’m nervous because I don’t really have documentation of anything.

I was originally interviewed over Zoom and fired over the phone. There’s no documentation of me being previously warned since it never happened but I also don’t have any proof that it didn’t happen… I’m nervous that they’re going to forge documents or something. There was also no handbook at the time of my firing, but I’m aware that since it happened they’ve created a handbook. I’m nervous they may try and backdate its creation and say that I explicitly broke handbook rules or something.
