13.1 Workers Compensation Statutory Background and Benefits

Why workers compensation exists

Workers compensation is a statutory, no-fault system. Before the laws, an injured worker had to sue the employer and prove negligence, while the employer raised three powerful common-law defenses: contributory negligence, assumption of risk, and the fellow-servant rule. These defenses defeated most claims, so injured workers often recovered nothing.

The workers compensation "bargain" replaced that lawsuit system. The worker gives up the right to sue the employer in tort; in exchange the worker receives statutory benefits regardless of fault — even if the worker caused the injury. This is the exclusive remedy doctrine: workers comp is the worker's sole recovery against the employer for a covered on-the-job injury.

Compensability: AOE/COE

An injury is covered only if it arises out of and in the course of employment (often abbreviated AOE/COE). "Arising out of" addresses the causal connection to the job; "in the course of" addresses the time, place, and circumstances. A worker hurt commuting to work normally is NOT covered (the going-and-coming rule), but a delivery driver hurt while driving for the employer is covered.

The four statutory benefit categories

State laws vary, but every act provides four benefit types. Part One of the workers compensation policy pays whatever the applicable state law requires — there is no dollar limit on Part One benefits.

Disability income classes

Disability income benefits split into four classes based on severity and permanence:

• Temporary Total (TT) — fully disabled now, expected to recover (most common).
• Temporary Partial (TP) — can do some work during recovery.
• Permanent Total (PT) — never able to return to gainful employment.
• Permanent Partial (PP) — a lasting impairment, often paid by a scheduled-injury table (e.g., loss of a hand = X weeks of benefits).

Most states pay disability income as roughly 66 2/3% (two-thirds) of the worker's average weekly wage, subject to a state maximum and minimum, after a short waiting period (commonly 3 to 7 days).

Worked example: weekly indemnity

A worker earns an average weekly wage of $900. The state pays 66 2/3% of AWW for temporary total disability, subject to a state maximum of $1,100/week.

Benefit = 0.6667 x $900 = $600 per week. Because $600 is below the $1,100 cap, the worker receives the full $600. If the same worker earned $2,000 AWW, two-thirds would be $1,333, but the state maximum of $1,100 would apply instead. The maximum is the trap — high earners are capped.

Second-Injury Funds and Subrogation

Many states maintain a second-injury (subsequent-injury) fund so that when a worker with a pre-existing disability suffers a new injury producing a greater combined disability, the employer pays only for the new injury and the fund covers the excess. The purpose is to encourage hiring workers with prior impairments. The WC insurer also retains subrogation against negligent third parties (a defective-machine maker), recovering what it paid the worker.

Coverage of Occupational Disease

Beyond sudden accidents, WC covers occupational disease — illness arising from workplace exposure (asbestosis, repetitive-stress carpal tunnel, hearing loss). Because disease has a long latency, states apply last-injurious-exposure rules to decide which employer/insurer pays. This ties to the Part Two three-part limit, where "bodily injury by disease" carries both an each-employee and an aggregate policy limit.

Worked Scheduled-Injury Benefit

Permanent-partial benefits often follow a statutory schedule: e.g., loss of a hand = 200 weeks of benefits. A worker earning a $600 weekly indemnity who loses a hand receives 200 × $600 = $120,000 in scheduled PP benefits, separate from medical and any temporary-total period already paid. Scheduled awards do not require proof of actual wage loss — the schedule fixes the value.

Going-and-Coming and Personal-Comfort Rules

Two doctrines decide borderline compensability. The going-and-coming rule denies benefits for ordinary commuting injuries — the worker is not yet "in the course of employment." Exceptions restore coverage when the employer pays for travel, the worker is on a special errand, or has no fixed workplace. The personal-comfort doctrine keeps a worker covered during reasonable on-premises breaks (restroom, brief meal, coffee). Fact patterns testing "hurt while commuting" (not covered) versus "hurt on a lunch break at the plant" (covered) are common.

Exclusive Remedy and Its Exceptions

The exclusive-remedy bar protects the employer from tort suits by the injured worker — but not in the narrow situations (intentional injury, dual capacity, third-party-over) that route to Part Two. Co-employees are generally immune too. The exam ties the no-fault benefit bargain (Part One) to the handful of cracks that revive a fault-based suit (Part Two).

Survivor (Death) Benefits Detail

When a covered injury causes death, WC pays funeral/burial expense (a state-capped amount) plus survivor income benefits to dependents — typically a percentage of the worker's average weekly wage paid to a surviving spouse (often until death or remarriage) and to minor children (often until age 18 or longer if a student). These benefits are part of the unlimited Part One statutory obligation. The exam contrasts death benefits (paid to dependents, percentage of AWW) with disability income (paid to the living worker).

Maximum Medical Improvement and Permanency

Disability income classes turn on maximum medical improvement (MMI) — the point at which the condition has stabilized. Before MMI, benefits are temporary (TT/TP); at MMI any lasting impairment becomes permanent (PT/PP), often rated by an impairment guide and, for scheduled losses, paid from the statutory schedule. Recognizing that the temporary/permanent line is drawn at MMI is a tested clinical-to-benefit linkage.
