13.1 Workers Compensation Statutory Background and Benefits
Key Takeaways
- Workers compensation is the employee's exclusive remedy: the worker gives up the right to sue the employer in tort in exchange for automatic no-fault benefits.
- Injury must arise out of and in the course of employment (AOE/COE); employer negligence need not be proven.
- Four statutory benefits: medical (unlimited), disability income (% of wage with caps), rehabilitation, and death (capped burial + survivor income).
- Monopolistic state funds are North Dakota, Ohio, Washington, and Wyoming (N-O-W-W); their policies exclude Part Two, requiring Stop Gap coverage.
- Income benefits run roughly 66 2/3% of average weekly wage, subject to a statutory weekly max/min and a waiting period; medical has no waiting period.
Why Workers Compensation Exists
Before workers compensation statutes, an injured employee had to sue the employer and prove negligence. Employers defended with three common-law defenses that made recovery nearly impossible: contributory negligence (any worker fault barred recovery), the fellow-servant rule (employer not liable for a co-worker's negligence), and assumption of risk (the worker knowingly accepted job hazards). Early-twentieth-century state laws replaced this with a no-fault bargain that every exam tests as the exclusive remedy doctrine.
The Exclusive Remedy Bargain
Under the statutory deal, the employee gives up the right to sue the employer in tort (and the chance at a large pain-and-suffering verdict). In exchange, the employee gains automatic, no-fault benefits: the worker need not prove employer negligence, only that the injury arose out of and in the course of employment (the "AOE/COE" test). Workers compensation becomes the employee's sole remedy against the employer. Tort suits against negligent third parties (e.g., a machine maker) are still allowed, with the insurer holding subrogation rights to be repaid from any recovery.
Statutory vs. Monopolistic vs. Competitive States
Workers compensation is a statutory line: the benefits are set by each state's law, not by the policy. There is no policy limit on Part One because the insurer promises to pay whatever the statute requires. Exam states fall into three buckets:
- Competitive (open) states — private insurers, or a state fund competing with them, write the coverage (most states).
- Monopolistic states — employers must buy from a state fund and cannot use private WC insurers: North Dakota, Ohio, Washington, Wyoming (mnemonic: N-O-W-W). In these states, Employers Liability (Part Two) is NOT included in the state-fund policy, so a separate Stop Gap endorsement on the CGL supplies that protection.
- State-fund-as-competitor states have a fund that competes with private carriers.
The Four Statutory Benefit Categories
Every state law provides four benefit types. Memorize them; exams ask which benefit fits a fact pattern.
| Benefit | What it pays | Key exam point |
|---|---|---|
| Medical | All reasonable medical care | Unlimited — no dollar cap and no time limit |
| Disability (income) | Lost wages while disabled | Paid as a % of wage, subject to a state max/min and a waiting period |
| Rehabilitation | Vocational/physical retraining | Returns worker to employment |
| Death | Burial allowance + survivor income | Burial benefit is capped by statute; survivor income to dependents |
Disability Classes and the Waiting Period
Income benefits are classed by severity and duration:
- Temporary Total (TTD) — fully disabled but expected to recover (most common claim).
- Temporary Partial (TPD) — can do light/part-time work while healing.
- Permanent Total (PTD) — never able to work again.
- Permanent Partial (PPD) — keeps a lasting impairment (e.g., lost finger) but can still work; often paid by a schedule of injuries assigning set weeks to each body part.
Most states impose a waiting period (commonly 3–7 days) before income benefits begin. If the disability lasts beyond a longer retroactive period, benefits are paid back to the date of injury. Medical benefits have no waiting period.
A Worked Disability Calculation
Suppose a state pays TTD at 66 2/3% of the average weekly wage (AWW), with a weekly maximum of $1,100. A worker earning $900/week:
- 66 2/3% of $900 = $600/week (below the $1,100 cap, so $600 is paid).
A higher earner at $1,800/week:
- 66 2/3% of $1,800 = $1,200, but the statutory max is $1,100, so only $1,100/week is paid.
The cap is why high earners receive proportionally less. Note WC income benefits are generally income-tax-free, partly explaining the 66 2/3% (rather than 100%) replacement rate.
The Four Benefit Categories
Workers compensation statutes pay benefits on a no-fault basis. The exam expects you to name the four categories:
| Benefit | Pays for |
|---|---|
| Medical | Reasonable, necessary medical care — usually unlimited with no deductible |
| Disability income | Lost wages, replacing a percentage (often 66 2/3%) of the average weekly wage, subject to a state maximum |
| Rehabilitation | Vocational/physical rehab to return the worker to employment |
| Death | Burial allowance plus survivor benefits to dependents |
The Four Disability Classes
Disability income is further classified by severity and duration:
- Temporary Total (TTD) — fully unable to work for a limited time (most common).
- Temporary Partial (TPD) — can do reduced work temporarily.
- Permanent Total (PTD) — never able to return to gainful work.
- Permanent Partial (PPD) — a lasting impairment but able to work; often paid by a scheduled award for loss of a specific body part.
The Exclusive-Remedy Bargain
The foundation of the entire system is the exclusive remedy doctrine: in exchange for guaranteed, no-fault benefits, the employee gives up the right to sue the employer for negligence. The employer accepts certain, limited liability and avoids unpredictable jury verdicts. This trade-off explains why benefits are statutory and capped, why fault is irrelevant, and why Part Two (employers liability) exists only for the narrow situations that fall outside the exclusive remedy — the conceptual key to the whole chapter.
Coverage Triggers: Accident vs. Occupational Disease
Workers comp responds to two kinds of work-related harm: an accident (a sudden, identifiable event such as a fall) and an occupational disease (a condition arising gradually from the work environment, such as hearing loss or repetitive-stress injury). Occupational disease can surface years after exposure, raising "last exposure" questions about which insurer responds. The injury must arise out of and in the course of employment (the "AOE/COE" test) to be compensable — an off-duty injury at home does not qualify, while one occurring during work duties does. This causation test is the gateway every comp claim must pass.
In a monopolistic state-fund state such as Ohio, how does an employer obtain Employers Liability protection?
A worker earns $1,500 per week in a state paying 66 2/3% of AWW for temporary total disability, with a $950 weekly maximum. What weekly benefit is paid?
