13.1 Workers Compensation Statutory Background and Benefits

The Exclusive Remedy Bargain

Workers' compensation is a state-mandated, no-fault system: an injured employee receives defined benefits without proving employer fault, and in exchange surrenders the right to sue the employer in tort. This trade is the exclusive remedy doctrine and is the single most-tested concept on the national portion.

Exam Key: No-fault runs both ways. The worker need not prove negligence, and the employer cannot raise common-law defenses (contributory negligence, assumption of risk, the fellow-servant rule). Those defenses were abolished when comp statutes replaced the old tort system.

Why the System Exists

Before comp laws (most enacted 1911–1948), an injured worker had to sue and overcome three employer defenses. The grand bargain replaced that uncertain lottery with a predictable benefit schedule. Coverage is compulsory for most employers in every state except Texas, where it is elective; an employer that opts out ('nonsubscriber') loses the common-law defenses and can be sued.

Most statutes set a numerical threshold — an employer becomes subject once it has a minimum number of employees (often three to five, varying by state). Below that count the employer may be exempt or may elect coverage voluntarily. The takeaway for the exam is that comp is the default and broadly mandatory, and the few elective or threshold situations are the exceptions, not the rule.

The Compensability Test: AOE/COE

Before any benefit is owed, the injury must arise out of and in the course of employment (AOE/COE) — memorize this phrase.

• Arising out of employment (AOE): a causal link — the job created or increased the risk of harm.
• In the course of employment (COE): the right time, place, and circumstance — the worker was doing the job.

The coming-and-going rule is the classic application: an ordinary commute is not in the course of employment, so a crash driving to work is usually not compensable. Exceptions restore coverage:

Part One also pays occupational disease (hearing loss, repetitive-motion, certain respiratory illness) — conditions developing over time from exposure greater than the public faces — not only sudden accidents.

The Four Benefit Categories

1. Medical Benefits

• 100% of reasonable and necessary treatment; no dollar cap, no deductible, no copay
• No waiting period — owed from the moment of injury

2. Disability (Wage Replacement)

Standard rate is 66 2/3% (two-thirds) of the Average Weekly Wage (AWW), subject to a state weekly maximum and minimum. Four classes:

3. Death Benefits

Wage benefit to surviving dependents plus a burial/funeral allowance (commonly $5,000–$10,000 by state).

4. Rehabilitation

Medical rehab restores function; vocational rehab retrains when the worker cannot return to the former job.

Worked Wage Calculations

Average Weekly Wage (AWW) = gross earnings over the statutory look-back (often 13 or 52 weeks) divided by the weeks; it includes overtime, bonuses, and tips.

TTD example: AWW = $1,500 → benefit = $1,500 × 66 2/3% = $1,000/week.

TPD example: Pre-injury AWW = $1,500; light-duty earnings = $900 → wage loss $600 → benefit = $600 × 66 2/3% = $400/week.

Wage benefits begin after a waiting period of 3–7 days (state-specific); medical has none. Beyond the retroactive trigger (commonly 14–21 days) the carrier pays the waiting days back to day one. Comp wage benefits are non-taxable, so two-thirds of gross nearly equals prior take-home.

Scheduled vs. Non-Scheduled and MMI

Scheduled PPD pays fixed statutory weeks for a named body part (e.g., loss of a hand) even if the worker loses no wages. Non-scheduled PPD pays on percentage loss of earning capacity (back, head). Maximum Medical Improvement (MMI) is when the condition stabilizes — it ends temporary benefits and triggers a permanent impairment rating; it does not mean full recovery.

The Exclusive-Remedy Bargain

Workers' compensation rests on a statutory trade-off: the employee gives up the right to sue the employer in tort in exchange for guaranteed, no-fault benefits for work-related injury or disease. This exclusive remedy is the conceptual core the exam returns to - the employee need not prove employer negligence, and contributory negligence is no defense, but recovery is limited to the statutory benefit schedule rather than open-ended tort damages.

The Four Categories of Benefits

Disability Income Classifications

Disability benefits are graded into four classes the candidate must distinguish: Temporary Total (TTD) - fully but temporarily unable to work; Temporary Partial (TPD) - working at reduced capacity during recovery; Permanent Total (PTD) - never able to return to gainful work; and Permanent Partial (PPD) - a lasting impairment that still allows some work, often paid by a scheduled loss table (so many weeks for loss of a hand, eye, etc.) or an unscheduled percentage of disability.

Covered Injuries and the "Arising Out Of" Test

A claim is compensable only if the injury arises out of and in the course of employment (AOE/COE). "Arising out of" links the injury to a work risk; "in the course of" ties it to the time, place, and activity of employment. Occupational disease is covered when it results from work exposure. The exam tests boundary cases - injuries during the commute (generally not covered under the "going and coming" rule), at company events, or from horseplay - where the AOE/COE test decides compensability.
