Illinois workers’ compensation may cover reasonable medical treatment, a portion of lost wages, temporary disability benefits, permanent disability benefits, and vocational support when appropriate. Construction workers may also have a separate third-party claim if another contractor, equipment manufacturer, property owner, or driver contributed to the accident. Marker Law evaluates both paths to protect your full recovery.
