13.5 Workers Comp Exclusions and Endorsements

Key Takeaways

  • Exclusions live in Part Two, not Part One: contractual liability, statutory penalties (OSHA/ERISA/COBRA), intentional injury, and illegal/underage employment are barred.
  • Knowingly employing a worker in violation of law (e.g., underage) voids Part Two coverage for that injury.
  • Part One has no policy exclusions, but the statute denies benefits for intoxication-caused, self-inflicted, or worker-initiated horseplay injuries; ordinary negligence never bars a claim.
  • The Voluntary Compensation Endorsement (WC 00 03 11) offers statutory-schedule benefits to non-required workers; a rejected offer shifts the claim to Part Two.
  • Memorize key forms: USL&H WC 00 01 06, OCSLA WC 00 01 09, Waiver of Subrogation WC 00 03 13.

What Part Two Excludes

Part One has essentially no exclusions because it tracks the statute. The exclusions live in Part Two — Employers Liability, which is the liability section. The exam expects you to recognize the major Part Two exclusions:

Quick Answer: Part Two does not pay for liability assumed by contract, punitive damages tied to knowingly employing someone illegally, intentional injury caused by the insured, fines/penalties under federal statutes (OSHA, ERISA, COBRA, the migrant act), or injury to a worker knowingly employed in violation of law.

The Key Part Two Exclusions

ExclusionWhat It Bars
Contractual liabilityLiability the insured assumes under a contract
Statutory penaltiesFines under OSHA, ERISA, COBRA, migrant/seasonal worker acts
Intentional injuryBodily injury intentionally caused or aggravated by the insured
Illegal employmentInjury to a worker knowingly employed in violation of law (e.g., underage)
Federal-act obligationsFELA, Jones Act, USL&H liability (handled by endorsement, not Part Two)
Outside the coverage territoryInjury occurring outside listed states/U.S. operations

The employer who knowingly hires an underage or undocumented worker injured on the job loses Part Two defense and indemnity — a recurring exam scenario.

Conduct That Bars a Part One Claim

While Part One has no policy exclusions, the underlying statute denies benefits for narrow worker misconduct. Distinguish these from ordinary negligence, which never bars a claim:

  • Intoxication that is the proximate cause of the injury.
  • Intentional self-inflicted injury.
  • Horseplay initiated by the injured worker (not merely a bystander to it).
  • Injury occurring while committing a crime or violating a positive safety order in some states.

The trap remains: the worker's careless violation of a routine safety rule does NOT defeat benefits — only the enumerated statutory bars do.

Common Endorsements

Endorsements tailor the policy. Memorize the form numbers most likely tested:

EndorsementFormPurpose
Voluntary CompensationWC 00 03 11Pay benefits to workers not required to be covered
USL&H CoverageWC 00 01 06Add federal longshore/harbor coverage to Part One
Outer Continental Shelf (OCSLA)WC 00 01 09Offshore federal coverage
Foreign Voluntary Comp(separate policy)Employees working abroad
Waiver of SubrogationWC 00 03 13Insurer waives recovery against a named third party
Sole Proprietors/PartnersWC 00 03 10Elect to include owners normally excluded

The Voluntary Compensation Endorsement does NOT make the worker subject to the statute; it simply offers to pay statutory-schedule benefits. If the worker rejects the benefit and sues, the claim shifts to Part Two.

Worked Endorsement Scenario

A farm owner in a state that exempts agricultural labor from mandatory workers comp wants to protect field workers and also requires waiver of subrogation in a packing contract.

  • Because the statute does not require coverage for farm labor, the owner adds the Voluntary Compensation Endorsement (WC 00 03 11), which offers benefits on the statutory schedule as if the workers were covered.
  • If an injured field worker accepts the voluntary benefit, it is paid like a Part One claim. If the worker rejects it and sues the employer, the claim becomes a Part Two liability matter (subject to the 100/500/100 limits).
  • To satisfy the packing contract, the owner adds the Waiver of Subrogation Endorsement (WC 00 03 13), so the insurer gives up its right to recover from the named packing company after paying a claim.

The lesson: voluntary comp converts an exempt class into a covered-by-election class, and waiver of subrogation is a contractually driven add-on, not automatic.

Waivers come in two flavors tested on the exam: a specific (designated person/organization) waiver names one entity, while a blanket waiver covers anyone the insured agreed in writing to protect before a loss. Carriers charge an additional premium percentage for the waiver because giving up subrogation forfeits a recovery source. Subrogation in workers comp lets the insurer, after paying benefits, step into the worker's shoes and sue the at-fault third party to recoup — the waiver surrenders exactly that right against the named party.

WC Exclusions and Limits of Part One

Although Part One pays statutory benefits without a dollar limit, certain situations fall outside coverage or require endorsement:

SituationTreatment
Serious and willful misconduct of the employerPenalties may be uninsurable
Knowingly employing in violation of law (illegal employment of minors)Excluded penalties
Failure to comply with health/safety lawIncreased benefits may be the employer's own cost
Voluntary compensation (employees not subject to WC law)Added by Voluntary Compensation endorsement
Employees in other/federal jurisdictionsOther-states, USL&H, maritime endorsements

Key WC Endorsements

  • Voluntary Compensation - extends WC-style benefits to workers not required to be covered (e.g., domestic or farm labor exempt from the statute), letting the employer offer benefits and avoid tort suits.
  • USL&H Coverage - adds longshore/harbor-worker exposure.
  • Maritime / Jones Act Coverage - covers seamen's negligence claims.
  • Foreign Voluntary Compensation - for employees working abroad.
  • Waiver of Our Right to Recover (Subrogation Waiver) - the insurer gives up subrogation against a designated party, often required by contract.

Subrogation in WC

When a third party causes a covered work injury, the insurer pays the employee's benefits and then subrogates against the at-fault third party. The Waiver of Subrogation endorsement waives that right against a specified contracting party.

Worked Example

A homeowner hires occasional domestic help exempt from the state WC statute and wants to provide benefits anyway. A Voluntary Compensation endorsement lets the policy pay WC-style benefits to that worker even though the law does not require it, and it discourages a tort suit. Separately, a delivery driver is injured by another motorist's negligence; WC pays the driver's benefits, then the insurer subrogates against the at-fault motorist's auto carrier to recover what it paid. Knowing which exposures need endorsements (voluntary comp, USL&H, waiver of subrogation) is the tested skill.
