13.1 Workers Compensation Statutory Background and Benefits

Why workers compensation exists

Before workers compensation laws, an injured employee had only one remedy: sue the employer for negligence. That route was slow, expensive, and easy for employers to defeat using the three common-law defenses — contributory negligence, the fellow-servant rule, and assumption of risk. Most workers recovered nothing.

Every state responded with a workers compensation statute that created a no-fault system. The employee gives up the right to sue the employer; in exchange, the employer must pay statutory benefits for any injury or disease arising out of and in the course of employment (the AOE/COE test), regardless of who was at fault. This trade-off is called the exclusive remedy doctrine.

Compulsory vs. elective; monopolistic vs. competitive

Most states have compulsory laws — covered employers must provide benefits. A few historically allowed elective coverage, where an employer that opts out loses the three common-law defenses (a powerful incentive to opt in). Texas remains the notable state where private-sector coverage is genuinely optional (non-subscribers).

States are also classified by how coverage is obtained:

• Monopolistic state funds — the employer must buy WC from the state fund; private insurers may not write the statutory coverage. The traditional monopolistic states are North Dakota, Ohio, Washington, and Wyoming (Puerto Rico and the U.S. Virgin Islands as well). Employers Liability (Part Two) is NOT included in monopolistic-fund policies, so a stop-gap endorsement on the CGL is used to fill that hole.
• Competitive state funds — a state fund competes with private insurers (e.g., California, New York). The employer may buy from either.

The four benefit categories

Workers compensation statutes pay benefits with no dollar maximum on medical and statutory formulas for lost wages. Memorize the four buckets:

Disability income is further split into four types: Temporary Total (TTD), Temporary Partial (TPD), Permanent Total (PTD), and Permanent Partial (PPD). PPD is frequently paid under a scheduled-injury table (e.g., loss of a hand = a fixed number of weeks of benefits) versus non-scheduled injuries paid as a percentage of disability.

Worked benefit example (disability income)

An employee earns an average weekly wage (AWW) of $900. The state pays TTD at 66 2/3% of AWW, subject to a state maximum of $1,100/week.

• Calculated benefit: $900 x 0.6667 = $600/week.
• The $600 is below the $1,100 cap, so the worker receives $600/week, tax-free.

Now assume a higher earner with AWW of $2,400:

• Calculated benefit: $2,400 x 0.6667 = $1,600/week, BUT the state maximum of $1,100 applies.
• The worker receives $1,100/week, not $1,600. High earners are capped — a common exam trap.

The two-part bargain in detail

The exclusive-remedy bargain runs in both directions and the exam tests both halves. For the employee, the upside is certainty: no need to prove the employer was negligent, no contributory-negligence defense, prompt medical care, and tax-free wage replacement. The downside is that benefits are limited to the statutory schedule — no pain and suffering, no jury verdicts, no punitive damages against the employer.

For the employer, the upside is tort immunity — the employee cannot sue for negligence. The downside is strict, no-fault liability for every covered injury, even ones the employee partly caused. This is why misreading the bargain (e.g., thinking an injured worker can both collect benefits and sue the employer) is a frequent wrong answer.

Who and what is covered

Coverage applies to employees, defined broadly by each state, for injuries that meet the AOE/COE test. 'Arising out of employment' means the work caused or contributed to the injury; 'in the course of employment' means it happened at the time, place, and while doing something for the employer. Both prongs must be satisfied.

Common coverage edges and traps:

• Occupational disease (e.g., asbestosis, repetitive-stress) IS covered, even though it develops over years rather than in one accident.
• Going-and-coming rule: ordinary commuting is generally NOT covered, but a special errand or employer-provided travel may be.
• Horseplay and intoxication: injuries from the worker's own intoxication or willful misconduct are often denied by statute.
• Coverage thresholds vary — many states exempt very small employers (e.g., fewer than 3-5 employees) or certain farm/domestic workers.

The four disability-income types

Disability income is the most-tested benefit detail. Match the label to the fact pattern:

PPD is split into scheduled injuries (a fixed number of weeks per body part — e.g., a thumb = X weeks) and non-scheduled injuries (a percentage-of-the-whole-body rating). 'Temporary vs. permanent' answers will the worker recover; 'total vs. partial' answers can the worker do any work.
