Any determination made by the UIA concerning an employer's liability, the coverage of a worker's services, an employer's tax rate, or the payment of benefits to a worker, can be appealed. After a "determination" is issued, a protest may be filed and a "redetermination" is issued. From a Redetermination, the matter may be appealed to an Administrative Law Judge.
The protest or appeal must be in the UIA's possession (not merely postmarked) within 30 calendar days after the determination or redetermination was mailed or personally served.
The UIA has published a booklet to help employer and claimants in preparing for a Referee hearing. The booklet is called "A Guide to UIA Appeals Hearings" and is mailed with every Notice of Hearing.
