Yes, the unemployment hearing is with a judge (ALJ). It's informal, sort of like the People's Court on TV. Basically, each side tells their story and the ALJ rules. Practically every unemployment claim goes to the judge, because if the claim is granted, the employer appeals, and if denied, the employee appeals.
The employer probably will claim that you were trying to avoid admitting arriving late to work. You can claim that to the extent you made any mistakes, that's all they were, it does not prove you were actually late to work, and that because the employer was not damaged by your errors, you cannot be denied unemployment benefits.
Hope this helps.
