## 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. [9](https://content.naic.org/insurance-topics/workers%27-compensation-insurance "Workers’ Compensation Insurance") [10](https://content.naic.org/consumer/small-business.htm "Small Business Insurance") [11](https://www.dir.ca.gov/dwc/Employer.htm "DWC employer information") [12](https://www.tdi.texas.gov/wc/employer/index.html "Employer resources")

## Key Differences in Workers’ Compensation Insurance

### Construction Practice and Casualty Placement

Aon describes workers’ comp within a global construction practice for contractors, owners, engineers and project participants. Marsh McLennan Agency places the line within its broader casualty practice. The first record specifies a construction focus; the second situates the coverage among casualty lines. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [8](https://www.marshmma.com/us/solutions/casualty.html "Comprehensive Casualty Cover")

### Claims and Risk Analytics

Marsh McLennan Agency lists risk consulting, data-driven claims management and risk analytics across its casualty program, including workers’ comp. Aon describes project risk advice but does not detail workers’ comp claims analytics. Ask what injury trends, experience-modifier data and return-to-work support each service covers. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [8](https://www.marshmma.com/us/solutions/casualty.html "Comprehensive Casualty Cover")

### Specialist Engagement

Marsh McLennan Agency says clients work directly with a casualty specialist in an adviser-led placement. Aon describes global broking and market access without a quote flow. Confirm who handles submission and remains the claim contact after binding. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [8](https://www.marshmma.com/us/solutions/casualty.html "Comprehensive Casualty Cover")
