## What Is Aon?

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

## Key Differences in Workers’ Compensation Insurance

### Construction account or small-business product

Aon describes workers’ comp within a global construction practice serving contractors, owners and engineers. Chubb directly underwrites the line for small businesses with one employee through $30 million in revenue, including technology classes. Construction buyers should check whether their revenue and class fit Chubb’s stated range. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [7](https://www.chubb.com/us-en/business-insurance/workers-compensation-small.html "Workers' Compensation Insurance for Small Business")

### Claims services and policy pairing

Chubb says the policy can pair with a Chubb BOP and describes nurse case managers, return-to-work support, pharmacy management and preferred-provider access. Aon describes project risk advice but no workers’ comp medical or claim services. Ask which Chubb services apply to the account and whether the policy can be paired. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [7](https://www.chubb.com/us-en/business-insurance/workers-compensation-small.html "Workers' Compensation Insurance for Small Business")

### Quote access and limits

Chubb accepts online quote requests or applications through appointed agents and brokers; it describes varied employer-liability limits without specific figures. Aon describes broking but no application flow or limits. Request the proposed limits and carrier details. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [7](https://www.chubb.com/us-en/business-insurance/workers-compensation-small.html "Workers' Compensation Insurance for Small Business")

## What to Confirm in Workers’ Compensation Insurance Quotes

- Ask Chubb whether the construction class and revenue fit and request employer-liability limits. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [7](https://www.chubb.com/us-en/business-insurance/workers-compensation-small.html "Workers' Compensation Insurance for Small Business")
- Ask Aon for the proposed carrier, quote path and claim support. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [7](https://www.chubb.com/us-en/business-insurance/workers-compensation-small.html "Workers' Compensation Insurance for Small Business")
