Key Differences in Employment Practices Liability Insurance

Placement and Intended Organizations

Liberty Mutual includes EPL in its ProShield management-liability package, scoped to private and nonprofit organizations. Aon describes helping professional-services firms arrange or assess EPL, without stating whether its placements are packaged. This makes the purchase structure a key distinction: ask Liberty Mutual which other management-liability parts accompany EPL, while an Aon buyer should establish whether the proposed placement is standalone or combined. 3 6

Policy Detail and Buyer Questions

Liberty Mutual describes ProShield as one package policy intended to reduce the need for separate endorsements and notes selected EPL features such as third-party coverage. Aon describes workplace-wrongdoing risk and customized coverage solutions but does not list policy features or insured groups. The package overview does not settle how terms coordinate across coverage parts; ask for the declarations and policy wording before deciding whether bundled structure meets your needs. 3 6

What to Confirm in Employment Practices Liability Insurance Quotes

  • Ask Liberty Mutual which coverage parts and third-party terms are included in your ProShield quote. Ask Aon to identify any package components, proposed insurer, and policy-specific limits and exclusions. 3 6
