Workers compensation is a form of insurance providing medical and wage-replacement benefits to employees who suffer job-related injuries or occupational illnesses. It's a mandatory system in most developed countries, managed at the state or provincial level in North America, with employers required to maintain coverage. The system balances worker protection with employer liability limits, creating a no-fault framework where injured workers receive benefits regardless of fault, while employers avoid most lawsuits. The field encompasses claims processing, fraud investigation, compliance management, regulatory reporting, and return-to-work coordination. Professionals in this space work across insurers, large employers, third-party administrators (TPAs), law firms, and government agencies.
