I don’t know about that state but I had an employer in my state (I mean the llc was from a different state) who challenged my unemployment. The same employer (the guy who owned the small business really) had a severance package I could have gotten if I would have signed a statement an action I took on his orders was my fault. Well I didn’t. He tried to say it was with cause to the unemployment office. Well long and short of it is I challenged the challenge and he had to respond with proof which he did not but it delayed getting any checks until I had another job and the unemployment checks that came were not meaningless they did just go toward paying late bills and again having some of a savings for emergency. Overall I lost money because if I had gotten the unemployment in a timely manner I would have been able to prevent late payments on bills. I would compare the process to challenging items on your credit report. The employer has the onus (at least in my state) to show proof.
