## What Is Workers’ Compensation Insurance?

Workers’ compensation can pay medical care and part of an employee’s lost wages after a work-related injury or illness. If you have staff, check who is covered in each state; owners, contractors and some workers may be treated differently. [7](https://content.naic.org/insurance-topics/workers%27-compensation-insurance "Workers’ Compensation Insurance") [8](https://content.naic.org/consumer/small-business.htm "Small Business Insurance") [9](https://www.dir.ca.gov/dwc/Employer.htm "DWC employer information") [10](https://www.tdi.texas.gov/wc/employer/index.html "Employer resources")

## Key Differences in Workers’ Compensation Insurance

### Broker Placement and Program Scope

Marsh McLennan Agency describes arranging workers’ compensation for commercial clients and says its support includes risk management focused on safety and prevention. Liberty Mutual lists workers’ compensation in its commercial catalogue, with products distributed through brokers and agents; its record does not specify a comparable safety program. Ask each adviser which prevention services apply to your business and who places the policy. [3](https://business.libertymutual.com/claims/policyholder-resources/workers-compensation-resources/ "Workers Compensation Resources") [6](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA")

### Eligibility and Quote Route

Marsh McLennan Agency directs businesses to contact an adviser or specialist, with state and class eligibility determined by placement. Liberty Mutual’s record likewise establishes broker/agent distribution but does not describe eligible classes or quote intake. Get written confirmation of state availability, class acceptance and the issuing insurer from each route.
