Workers' compensation and benefits policy
Workers' compensation is a form of insurance providing wage replacement and medical benefits to workers injured in the course of their employment. Eligibility for, and awarding of, benefits to injured workers are determined by workers’ compensation boards, which are funded through employer premiums.
