The Workers' Compensation Board (WCB) of Alberta provides insurance coverage for workers injured or made ill on the job. Funded by premiums paid by employers, WCB covers medical treatment, rehabilitation services, and wage replacement for workers unable to work due to workplace injuries or occupational diseases. In exchange for this coverage, workers give up the right to sue their employers for workplace injuries—a tradeoff that provides certainty for both parties. WCB also works on injury prevention, promoting workplace safety to reduce accidents before they happen. Every Canadian province has a similar workers' compensation system.
