13.1 Workers Compensation Statutory Background and Benefits

The Historical Bargain

Before workers compensation laws, an injured worker had to sue the employer and prove negligence. Employers defended with three powerful common-law defenses: contributory negligence (the worker's own fault barred recovery), assumption of risk (the worker accepted known dangers), and the fellow-servant rule (a coworker, not the employer, caused the harm). Most injured workers recovered nothing.

State legislatures replaced this with workers compensation (WC) statutes, beginning around 1911. The system is a trade-off often called the grand bargain: the worker surrenders the right to sue, and the employer surrenders its common-law defenses.

No-Fault and Exclusive Remedy

WC is a no-fault system. Benefits are paid regardless of whether the employer, the worker, or no one was negligent. Even a careless employee who causes the accident is covered.

The trade-off is the exclusive remedy doctrine: WC benefits are the worker's only remedy against the employer for a covered injury. The worker generally cannot also sue the employer in tort. Exam trap: exclusive remedy does not protect third parties (such as a negligent equipment manufacturer); the worker may still sue them, and the insurer may pursue subrogation against that third party.

The AOE/COE Coverage Trigger

An injury is compensable only if it arises out of and in the course of employment, abbreviated AOE/COE:

• Arising out of employment (AOE): there is a causal connection between the job and the injury.
• In the course of employment (COE): the injury happened at the time, place, and while doing what the job required.

Both prongs must be met. A heart attack while jogging at home fails both. A back strain while lifting inventory meets both. Occupational disease (such as asbestosis) is also covered when it results from work conditions, even though it develops over time rather than from a sudden accident.

The Five Statutory Benefit Categories

State statutes (not the policy) set the benefits. Memorize the five categories and the disability-income subtypes.

Disability income has four subtypes: Temporary Total (TTD), Temporary Partial (TPD), Permanent Total (PTD), and Permanent Partial (PPD).

Worked Example: Disability Income

Most states pay disability income as a percentage of average weekly wage (AWW), commonly 66 2/3%, subject to a statutory maximum and a waiting period.

Suppose a worker earns an AWW of $900 and the statutory rate is 66 2/3%. The weekly benefit is $900 x 0.6667 = $600, unless that exceeds the state maximum. If the state imposes a 7-day waiting period, no income benefit is owed for the first week, although medical benefits begin immediately. Many states add a retroactive provision: if disability lasts beyond a set period (e.g., 21 days), the worker is paid back for the waiting week.

The Four Disability Income Subtypes

Disability income is the most heavily tested benefit category. Memorize how the four subtypes differ on duration and degree of disability:

• Temporary Total Disability (TTD): the worker cannot work at all, but is expected to recover (a broken leg healing over weeks).
• Temporary Partial Disability (TPD): the worker can do reduced or light-duty work during recovery; benefits make up part of the lost wage.
• Permanent Total Disability (PTD): the worker can never return to gainful employment (loss of both hands, total blindness).
• Permanent Partial Disability (PPD): a permanent impairment that does not bar all work, often paid by a scheduled award (a fixed number of weeks per body part).

Scheduled vs. Unscheduled Awards

PPD claims are valued two ways. A scheduled award assigns a fixed number of weeks of benefits to the loss (or loss of use) of a listed body part — for example, a statute might allow 200 weeks for loss of a hand. If the worker's weekly rate is $600 and a thumb is worth 60 weeks, the award is 60 x $600 = $36,000.

An unscheduled (non-scheduled) award covers injuries not on the list, such as a back or head injury, and is valued by the impact on the worker's overall earning capacity. Exam trap: scheduled awards are usually paid regardless of whether the worker actually loses wages.

The five benefit categories applied

Workers compensation provides five statutory benefit types, and the exam tests how each is triggered: medical (unlimited, no deductible, no waiting period), disability income (a percentage of the average weekly wage), rehabilitation (vocational retraining), death benefits to dependents, and survivor/burial allowances. Disability income splits into four subtypes - temporary total, temporary partial, permanent total, and permanent partial - and permanent partial awards are often scheduled (a fixed number of weeks per body part) versus unscheduled (a percentage of the whole person for injuries like the back).

Course and scope: the AOE/COE trigger

Benefits apply only to an injury arising out of and in the course of employment (AOE/COE) - the injury must both arise from a work risk and occur within the time, place, and activity of the job. This trigger generates the classic exclusions: the going-and-coming rule denies coverage for an ordinary commute, horseplay and intoxication can break the connection, and a purely personal errand falls outside scope.

Worked disability example: a worker earning a $900 average weekly wage receives two-thirds, or $600 per week, in temporary total benefits, subject to the state maximum tied to the state average weekly wage. Anchoring on AOE/COE plus the two-thirds formula answers most benefit questions.
