This document discusses workers' compensation laws. It explains that workers' compensation is a no-fault system that provides insurance to cover workers injured on the job regardless of fault. It is intended to protect both employers and employees by compensating injured workers while protecting employers from costly lawsuits. The document outlines who is covered under workers' compensation (employees), what types of injuries or illnesses are covered (those occurring on the job or resulting from long-term occupational exposure), and the circumstances under which injured workers can file a workers' compensation claim or lawsuit against their employer or third parties.
