13.1 Workers Compensation Statutory Background and Benefits

The Compensation Bargain

Workers compensation is a statutory, no-fault system created in the early 1900s to replace the inefficient and adversarial common-law tort process. Before workers comp, an injured worker had to sue the employer and prove negligence, while the employer could escape liability through three powerful common-law defenses: contributory negligence, the fellow-servant rule, and assumption of risk. Most injured workers recovered nothing.

The modern system rests on the compensation bargain (also called the exclusive remedy): the employee surrenders the right to sue the employer in tort, and in exchange the employer guarantees prompt, defined benefits regardless of fault. The employer cannot raise the old defenses, and the worker cannot pursue pain-and-suffering or punitive damages against the employer.

Compensability: AOE and COE

For an injury to be compensable, it must arise out of employment (AOE) and occur in the course of employment (COE). Both prongs must be satisfied.

• Arising out of addresses causation — the injury's origin is connected to a risk of the job.
• In the course of addresses time, place, and circumstance — the injury happened while the worker was performing duties.

The going-and-coming rule generally excludes ordinary commuting because the worker is not yet performing job duties. Exceptions exist: a worker injured while running an errand for the employer (the special-errand exception) or one paid for travel time may be covered.

Quick Answer: Compensable = AOE and COE. A heart attack at home is neither; a fall on the warehouse floor is both.

The Four Benefit Categories

Every jurisdiction provides four core benefit types, and the exam expects you to distinguish them:

Medical benefits are the broadest: there is no dollar cap and no deductible. Disability income, by contrast, is capped — it replaces only a portion of wages so the worker retains an incentive to recover and return to work.

Disability Classifications and the Waiting Period

Disability income is divided into four classes by degree and duration:

• Temporary Total Disability (TTD) — cannot work at all, but will recover (the most common claim).
• Temporary Partial Disability (TPD) — can do limited/light-duty work while healing.
• Permanent Total Disability (PTD) — never able to work again; some states presume PTD for loss of both eyes, both hands, etc.
• Permanent Partial Disability (PPD) — a lasting impairment that does not prevent all work; often paid by a scheduled award (e.g., a set number of weeks for loss of a finger).

A waiting period (often 3 to 7 days) applies before indemnity (wage) benefits begin, discouraging trivial claims. If the disability lasts beyond a retroactive period, the carrier pays the waiting-period days retroactively. Medical benefits are never subject to the waiting period — care begins immediately.

Coverage Triggers and the Going-and-Coming Exceptions

Because compensability turns on AOE/COE, the exam drills the edge cases. The going-and-coming rule denies coverage for ordinary commuting, but several exceptions restore it: the special-errand rule (the worker is running a task for the employer), paid travel time, the dual-purpose trip (travel serves both personal and business ends), and injuries on the employer's premises or parking lot. Traveling employees (salespeople, technicians) are generally covered during the entire work trip, including reasonable meals and lodging, under the commercial-traveler doctrine.

Occupational disease is also compensable when it arises from the work environment over time (e.g., repetitive-stress injury, hearing loss, certain cancers), distinguishing it from an ordinary disease of life the general public faces equally. Trap: a heart attack triggered by extraordinary work exertion may be compensable, while one occurring at home from natural causes is not.

Benefit Calculation and Maximum/Minimum Caps

Disability income (indemnity) is the most calculation-heavy WC topic. The benefit is a percentage of the worker's average weekly wage (AWW) — most commonly 66⅔% — but every state imposes a statutory maximum (often tied to the state average weekly wage, SAWW) and a minimum. A high earner's benefit is therefore capped well below two-thirds of actual wages, while a low earner is lifted to the minimum.

Worked example: a worker earning $900/week in a state paying 66⅔% with a $700/week maximum receives $600 (66⅔% of $900 = $600, under the cap), so the maximum does not bite here.

Raise the wage to $1,200/week: 66⅔% = $800, but the $700 maximum applies, so the worker receives only $700. Trap: always test the computed benefit against the state maximum and minimum; the raw percentage is not always the payable amount. Death benefits similarly pay a percentage of AWW to dependents plus a burial allowance, subject to caps and a maximum number of weeks, after which benefits cease even if the dependents remain in need, unless the state provides for remarriage or dependency adjustments.
