Please attach a copy of the notice you received from your insurance company with this complaint form. Do you wish to request a hearing?The Illinois workers' compensation law is 820 ILCS 305. All forms related to the management of workers' compensation cases must be submitted in CompFile. All other forms should be mailed to: A waiver of subrogation means that a business and their insurance company is foregoing all rights to file suit, or seek damages, from another business. Most state workers' compensation laws, or cases construing them, allow the employer and its carrier to waive its right to subrogate against a third party. I represent Respondent, ABC Corporation, in the abovecaptioned workers' compensation cases. The purpose of workers' compensation subrogation is to ensure employees don't endure the financial burden of injuries and illness at work. The endorsed warrant and receipt is a full and complete acquittance to the Commission for the payment out of the Second Injury Fund.
