## 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. [10](https://content.naic.org/insurance-topics/workers%27-compensation-insurance "Workers’ Compensation Insurance") [11](https://content.naic.org/consumer/small-business.htm "Small Business Insurance") [12](https://www.dir.ca.gov/dwc/Employer.htm "DWC employer information") [13](https://www.tdi.texas.gov/wc/employer/index.html "Employer resources")

## What Are the Key Differences Between Gallagher and Marsh McLennan Agency Workers’ Compensation Insurance?

### How a Buyer Starts the Quote

Gallagher gives small-business buyers three ways to begin: an online quote form, a phone line to a small-business adviser, or a scheduled callback. It arranges coverage through partner carriers rather than underwriting it. MMA’s overview also describes adviser-led placement but does not list an online quote or callback route. If you need help assembling payroll and class details, Gallagher publishes both self-service and assisted entry points; MMA buyers should ask which adviser will own the placement. [6](https://www.gallaghersmallbusiness.com/insurance-products/workers-compensation/ "Workers' Compensation Insurance") [9](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA")

### Benefits and State Requirements

Gallagher describes medical costs, lost wages, retraining, related legal fees, and temporary-replacement wages among its workers’ compensation coverage description. It notes that state requirements and employee-count thresholds differ, including Texas employers’ ability to opt out. MMA describes workplace injury or death coverage and says class and state eligibility are placement-specific. Compare the quote against each state where employees work, and ask whether the employer-liability component responds when a state permits an opt-out. [6](https://www.gallaghersmallbusiness.com/insurance-products/workers-compensation/ "Workers' Compensation Insurance") [9](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA")

- How will MMA confirm state requirements and class codes, and what injury benefits will the proposed policy include? [9](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA")
