What is the primary purpose of worker's compensation insurance?

The primary purpose of worker's compensation insurance is to cover injuries to workers. This type of insurance provides financial support for employees who are injured or become ill as a result of their job. It typically covers medical expenses, rehabilitation costs, and a portion of lost wages due to time off work. Additionally, worker's compensation helps protect employers from lawsuits related to workplace injuries, as employees generally cannot sue their employers for injuries covered under worker's compensation policies.

The other options mention important aspects of risk management and protection in construction projects, but they do not align with the core function of worker's compensation insurance. Coverage for project property deals with damage insurance specific to the physical assets of the project, while protection against negligence claims is associated with liability insurance. The protection for subcontractors refers to different contractual and liability protections, not specifically to the coverage of worker injuries. Thus, focusing on injuries to workers captures the essential role of worker's compensation insurance accurately.
