13.1 Workers Compensation Statutory Background and Benefits
Key Takeaways
- Workers comp is a no-fault statutory system: the worker gets prompt benefits and gives up the right to sue (the 'grand bargain' / exclusive remedy).
- The acts removed the employer's three common-law defenses: contributory negligence, the fellow-servant rule, and assumption of risk.
- An injury must arise out of and in the course of employment (AOE/COE) to be compensable; occupational diseases qualify.
- Four benefit categories: medical (no limit, no waiting period), disability income (usually 66⅔% of wage, after a waiting period), death, and rehabilitation.
- Scheduled PPD pays a fixed number of weeks regardless of wage loss; non-scheduled PPD pays based on lost earning capacity.
The Grand Bargain
Workers compensation is a statutory, no-fault system created by state law. Before these acts, an injured worker had to sue the employer in tort and prove negligence — a fight the employer could defeat with three powerful common-law defenses: contributory negligence (the worker contributed to the injury), the fellow-servant rule (a co-worker, not the employer, caused it), and assumption of risk (the worker knew the job was dangerous). Workers comp removed all three defenses. In exchange, the worker gives up the right to sue the employer for negligence.
This trade-off is called the grand bargain or exclusive remedy: the worker receives prompt, predictable, no-fault benefits, and the employer receives immunity from negligence suits. Fault is irrelevant — a worker injured through pure carelessness is still covered, and an injury caused by the employer's negligence still pays only the statutory schedule, not a jury verdict.
Compensability: AOE/COE
For an injury to be covered it must arise out of and in the course of employment (the AOE/COE test). "Arising out of" speaks to causation — the work created the risk. "In the course of" speaks to time, place, and activity — the worker was on the job. A warehouse worker who throws out a back lifting a box is covered. The same worker injured playing weekend softball is not. Occupational diseases (asbestosis, repetitive-motion injuries, hearing loss) are covered when the exposure is connected to the work.
The Four Benefit Categories
Every state act provides four core benefits. Exam questions test which benefit applies to a fact pattern and how the dollar figures are calculated:
| Benefit | What it pays | Key trait |
|---|---|---|
| Medical | All reasonable medical care | No dollar limit, no waiting period — owed from moment of injury |
| Disability income | Wage replacement (TTD, PTD, TPD, PPD) | Usually 66⅔% of average weekly wage; subject to a waiting period |
| Death | Burial allowance + survivor benefits | Paid to dependents |
| Rehabilitation | Vocational/physical retraining | Return worker to gainful employment |
Disability income subdivides into four types: Temporary Total (TTD), Permanent Total (PTD), Temporary Partial (TPD), and Permanent Partial (PPD).
Waiting Periods and Scheduled vs. Non-Scheduled Awards
Wage-replacement benefits begin only after a waiting period (commonly 3 to 7 days). If the disability lasts beyond a longer retroactive period, the waiting days are paid back to day one. Medical benefits never have a waiting period.
Permanent partial disabilities split into two kinds. A scheduled injury (loss of a specific body part — hand, foot, eye) pays a fixed number of weeks set by statute regardless of actual wage loss, even if the worker returns at full pay. A non-scheduled ("whole-body" or "body as a whole") injury — a back or head injury — pays based on the percentage of lost earning capacity, because no fixed schedule fits.
The Four Disability Types in Detail
The exam expects you to match a fact pattern to the correct disability label:
- Temporary Total (TTD) — the worker cannot work at all but is expected to recover. This is the most common award; it pays the two-thirds wage benefit until the worker reaches maximum medical improvement (MMI) or returns to work.
- Temporary Partial (TPD) — the worker can do lighter or part-time work during recovery, earning reduced wages; the benefit makes up a portion of the wage gap.
- Permanent Total (PTD) — the worker can never return to gainful employment (e.g., loss of both hands, both eyes, or paralysis); benefits may continue for life.
- Permanent Partial (PPD) — a lasting impairment that does not prevent all work, paid as a scheduled or non-scheduled award.
The phrase maximum medical improvement is a key trigger: TTD generally ends and any PPD rating is assigned once the physician declares MMI.
Who Must Carry It, and the Second Injury Fund
Nearly every state mandates coverage once an employer has a threshold number of employees (often 1 to 5). An employer who fails to carry comp faces fines, stop-work orders, and personal tort liability — and forfeits the common-law defenses, exposing it to ordinary negligence suits. Sole proprietors, partners, and corporate officers may often elect in or out of their own coverage.
Many states also run a Second Injury Fund (Subsequent Injury Fund). It encourages employers to hire workers with a pre-existing disability: if such a worker is injured again and the combined disability is far greater than the new injury alone would cause, the employer pays only for the second injury and the fund pays the excess. Without it, employers would avoid hiring the already-disabled.
The Four Statutory Benefit Categories
State workers' compensation acts pay four kinds of benefits, all without regard to fault:
| Benefit | What it covers |
|---|---|
| Medical | Reasonable and necessary treatment, usually unlimited with no deductible |
| Disability (income) | Lost wages — Temporary Total, Temporary Partial, Permanent Total, Permanent Partial |
| Rehabilitation | Vocational and physical retraining to return to work |
| Death | Burial allowance plus survivor income to dependents |
Disability income is typically a percentage of the worker's average weekly wage (often around two-thirds), subject to state minimums and maximums and a short waiting period that is paid retroactively if disability persists.
A worker earning an average weekly wage of $1,200 is placed on temporary total disability. Ignoring the state maximum, what is the standard weekly benefit?
