Workers' compensation is a no-fault system of benefits paid by employers to workers who experience work-related injuries or diseases. 

The Illinois Workers' Compensation Commission resolves disputes between employees and employers regarding work-related injuries and illnesses.  A case is first tried by an arbitrator, whose decision may be reviewed by a panel of three commissioners. Cases may then be appealed to the circuit court, Appellate Court, and Illinois Supreme Court.  Like most court systems, the vast majority of disputes are resolved by settlement. 

Our staff will explain Commission procedures and case status information, but cannot answer specific legal questions regarding a case.  For more information, email us or call us 312-814-6500, Monday - Friday, 8:30 a.m. - 5:00 p.m. (Please do not fax questions.) 

Note:  All visitors to the Chicago and Springfield offices must show a valid photo ID.
