## Summary

CNA names claimant categories and HR resources; Aon describes a practice-level service for professional-services clients. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.cna.com/sites/default/files/assets/0bd3b7da-eb28-4142-aa13-d068f35e7a05/cna-employment-practices-liability.pdf?ContentCache=NONE&MOD=AJPERES "Employment Practices Liability | CNA")

## 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. [8](https://www.iii.org/article/employment-practices-liability-insurance "Employment Practices Liability Insurance") [9](https://asset.trvstatic.com/download/assets/epl-3001.pdf/2c354eaa63ca11eeacdd06e978c86228 "Employment Practices Liability Coverage") [10](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

CNA identifies private, nonprofit, and public organizations as potential EPL customers and lists allegations such as discrimination, harassment, retaliation, and employment-contract breach. Aon’s Professional Services Practice names law, accounting, and consulting firms as its audience and describes EPL as addressing workplace wrongdoing. If your organization is outside those professional-services categories, CNA’s stated customer classes are more explicit, though neither overview establishes your individual underwriting result. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.cna.com/sites/default/files/assets/0bd3b7da-eb28-4142-aa13-d068f35e7a05/cna-employment-practices-liability.pdf?ContentCache=NONE&MOD=AJPERES "Employment Practices Liability | CNA")

### Published Coverage and Services

CNA advertises Beyond HR resources and an employment-law helpline, while noting the helpline does not give legal advice on a specific act or claim; CNA also says coverage can extend to third-party discrimination or harassment and certain volunteer, intern, and contractor acts. Aon describes broader professional-services risk advice but does not list EPL-specific training or these covered groups. For a workforce with nonemployees, ask CNA how the proposed wording defines each group. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.cna.com/sites/default/files/assets/0bd3b7da-eb28-4142-aa13-d068f35e7a05/cna-employment-practices-liability.pdf?ContentCache=NONE&MOD=AJPERES "Employment Practices Liability | CNA")

## What to Confirm in Employment Practices Liability Insurance Quotes

- Ask CNA whether its helpline can address your scenario and which worker categories are insured. Ask Aon for the carrier, covered claimant groups, limit, and retention because its reviewed page does not specify policy wording. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.cna.com/sites/default/files/assets/0bd3b7da-eb28-4142-aa13-d068f35e7a05/cna-employment-practices-liability.pdf?ContentCache=NONE&MOD=AJPERES "Employment Practices Liability | CNA")
