13.2 Part One (Workers Comp) and Part Two (Employers Liability)

Key Takeaways

  • The standard form is the NCCI Workers Compensation and Employers Liability Policy (WC 00 00 00 C) with Part One and Part Two.
  • Part One pays statutory benefits to the worker with NO dollar limit, only for states listed in Item 3.A.
  • Part Two covers employer liability the statute did not bar (third-party-over, consortium, consequential injury) and HAS three dollar limits in Item 3.B.
  • The three Part Two limits are BI by Accident (each accident), BI by Disease (aggregate), and BI by Disease (each employee).
  • Exam trap: statutory benefit to employee = Part One; lawsuit/liability not barred by exclusive remedy = Part Two.

The Standard Policy: Two Insuring Agreements

The national exam tests the Workers Compensation and Employers Liability Insurance Policy (the NCCI standard form, edition WC 00 00 00 C). Its core is two distinct insuring agreements: Part One — Workers Compensation and Part Two — Employers Liability. Knowing what each does, and the gap between them, is the single most tested WC concept.

Part One — Workers Compensation

Part One says the insurer will pay promptly when due the benefits required of the insured by the workers compensation law. Key features:

  • No dollar limit — the insurer pays whatever the statute requires.
  • It applies only to the states listed in Item 3.A. of the Information Page.
  • The insurer pays first and then may seek reimbursement from the employer only for benefits the employer is legally required to provide but which exceed policy terms (rare).

Part Two — Employers Liability

Part Two covers the employer's liability for bodily injury by accident or disease that is not covered by the workers comp statute but for which the employer can still be sued. It fills the gaps where exclusive remedy does not bar a suit. Classic gap claims include:

  • Third-party-over actions — an injured worker sues a third party (e.g., a machine maker), who then sues the employer for contribution
  • Consequential bodily injury — injury to a family member flowing from the worker's injury
  • Dual-capacity suits and loss of consortium claims by a spouse

Part Two Limits — The Three Limits

Unlike Part One, Part Two has dollar limits, shown in Item 3.B. of the Information Page. There are three:

LimitApplies to
Bodily Injury by AccidentEach accident (all employees in one accident)
Bodily Injury by DiseaseAggregate (policy total for all disease claims)
Bodily Injury by DiseaseEach employee

A common written set is $100,000 / $500,000 / $100,000. Note: the By Accident limit is per accident (not per person), while the By Disease aggregate is the most the insurer pays for all disease claims during the policy period.

Worked Numeric — Applying the Three Limits

Limits are $100,000 each accident / $500,000 disease aggregate / $100,000 disease each employee.

  • Scenario A: A scaffold collapse injures 4 employees in one accident, and the employer is found liable to a third party for $300,000 total. The By Accident limit applies per accident, so the insurer pays only $100,000 for that single accident — regardless of how many employees were hurt.
  • Scenario B: Six employees develop an occupational disease; each has a $90,000 covered claim ($540,000 total). Each is within the $100,000 each employee limit, but the $500,000 disease aggregate caps total disease payments at $500,000.

Trap: Part One vs. Part Two

The most common exam trap is confusing the two parts. Remember:

  • Part One = unlimited, statutory benefits to the worker.
  • Part Two = limited (3 limits), pays a liability judgment to a third party or for a non-statutory suit.

If the question describes a benefit required by law and paid to the employee, it is Part One. If it describes a lawsuit or liability the statute did not bar, it is Part Two.

The Information Page

The NCCI standard policy has no traditional declarations page; instead it uses the Information Page, whose items the exam references directly. Item 1 names the insured and entity type; Item 2 sets the policy period; Item 3.A. lists the states where Part One statutory coverage applies now; Item 3.B. shows the three Part Two Employers Liability limits; Item 3.C. lists Other States coverage; and Item 4 identifies the classifications, rates, and estimated premium.

Knowing that 3.A. equals current statutory coverage and 3.C. equals standby coverage for states entered mid-term is essential, because a worker injured in a state listed in neither item creates an uncovered gap.

How the Two Parts Work Together

In most claims only Part One responds: the worker is hurt, exclusive remedy bars a tort suit, and the insurer pays unlimited statutory benefits. Part Two activates only when a lawsuit slips past exclusive remedy - a third-party-over action, a consortium claim by a spouse, or a dual-capacity suit.

Because Part Two pays a judgment rather than statutory benefits, it carries dollar limits while Part One does not. A single event can trigger both: the injured employee collects Part One benefits, and if a machine maker the employee sued turns around and sues the employer for contribution, Part Two responds to that liability up to its By Accident limit.

Who Is an Employee

Coverage turns on employment status, so the exam tests the employee versus independent contractor distinction. Statutory and right-to-control tests examine who directs the work, supplies tools, sets hours, and pays wages. Misclassifying a true employee as a contractor exposes the employer to uninsured statutory liability, while genuine independent contractors generally must carry their own coverage.

Borrowed-servant and leased-employee situations add complexity that endorsements and the alternate-employer endorsement address. When a staffing agency leases workers to a client, the alternate-employer endorsement extends the agency's coverage to protect the client as if it were the insured for those leased workers.
