[3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.chubb.com/content/dam/chubb-sites/chubb-com/us-en/global/forefront-portfolio-product-sheets/2021-09.03_Forefront_Portfolio_EPL.pdf "The ForeFront Portfolio — Employment Practices Liability Insurance")

## What Is Aon?

Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account. [1](https://www.aon.com/en/about/leadership-and-governance/brokerage-terms-of-service-for-commercial-risk-solutions-us "Commercial Risk Solutions U.S. Brokerage Terms of Service") [2](https://www.aon.com/en/capabilities/middle-market-clients "Middle Market Clients")

## What Is Employment Practices Liability Insurance?

EPLI can help pay covered defense costs and losses when applicants or workers allege discrimination, harassment, wrongful termination or other workplace wrongdoing. If you employ people, check the claim definition, defense costs and prior acts. [9](https://www.iii.org/article/employment-practices-liability-insurance "Employment Practices Liability Insurance") [10](https://asset.trvstatic.com/download/assets/epl-3001.pdf/2c354eaa63ca11eeacdd06e978c86228 "Employment Practices Liability Coverage") [11](https://asset.trvstatic.com/download/assets/lia-3001.pdf/e79a6b6c63ca11eeaa7806e978c86228 "Liability Coverage Terms and Conditions")

## Key Differences in Employment Practices Liability Insurance

### Arrangement and Buyer Fit

Chubb underwrites EPL as one of seven parts of its ForeFront Portfolio for private companies, nonprofits, and healthcare organizations. Aon’s reviewed material presents EPL as a line its Professional Services Practice helps arrange or advise on, with law, accounting, and consulting firms as its stated audience. A buyer should establish whether the proposed Chubb package fits the organization and whether Aon is approaching a comparable placement. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.chubb.com/content/dam/chubb-sites/chubb-com/us-en/global/forefront-portfolio-product-sheets/2021-09.03_Forefront_Portfolio_EPL.pdf "The ForeFront Portfolio — Employment Practices Liability Insurance")

### Published Coverage and Services

Chubb describes optional Duty to Defend wording and early-engagement expense coverage, plus ChubbWorks employment loss-prevention tools. Aon describes advisors using industry knowledge, data, and tools for risk-management and human-capital decisions, rather than naming a particular policy feature or EPL resource. These are different decision points: ask Chubb which defense option is quoted and ask Aon what advisory work applies to your placement. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.chubb.com/content/dam/chubb-sites/chubb-com/us-en/global/forefront-portfolio-product-sheets/2021-09.03_Forefront_Portfolio_EPL.pdf "The ForeFront Portfolio — Employment Practices Liability Insurance")

## What to Confirm in Employment Practices Liability Insurance Quotes

- Chubb places ForeFront through an appointed agent or broker; Aon does not publish a specific carrier, limit, or retention on the reviewed practice page. Request the issuing insurer and defense option in writing from either route. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.chubb.com/content/dam/chubb-sites/chubb-com/us-en/global/forefront-portfolio-product-sheets/2021-09.03_Forefront_Portfolio_EPL.pdf "The ForeFront Portfolio — Employment Practices Liability Insurance")

| --- | --- | --- |
| Role in This Line | Aon presents Employment Practices Liability as a line its Professional Services Practice helps arrange or advise on for professional-service firms.

[3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s global professional-services practice page.

This does not establish any specific policy grant. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s marketing description of the brokerage/coverage area.

| Risk Services | Aon says its professional-services advisors use industry knowledge, insights, data and tools to support risk-management and human-capital decisions.
