Missouri Workers' Compensation Insurance

Overview of Missouri Workers' Compensation

Missouri's workers' compensation system is governed by Chapter 287 of the Missouri Revised Statutes. The system provides a no-fault mechanism for compensating employees injured on the job while protecting employers from most workplace injury lawsuits.

Employer Coverage Requirements

General Requirement: 5 or More Employees

Missouri requires workers' compensation coverage for:

  • Private employers with 5 or more employees
  • Employee count includes all full-time, part-time, and seasonal workers
  • Out-of-state employers with employees working in Missouri

Construction Industry Exception

All construction industry employers must provide workers' compensation coverage:

  • Regardless of the number of employees
  • Even sole proprietors with one employee

  • Broader definition of construction activities
Employer TypeCoverage Required

  • Employers with fewer than 5 employees (non-construction)
  • Domestic servants in private homes
  • Some agricultural workers
  • Certain real estate agents (independent contractors)
  • Corporate officers (may elect out with proper documentation)

Exam Tip: The construction industry exception is critical for the exam. Remember that ALL construction employers must have workers' comp coverage regardless of how many employees they have.

The No-Fault System

How No-Fault Works

Missouri workers' compensation operates as a no-fault system:

  • Benefits paid regardless of who caused the accident
  • Employer negligence not required for coverage
  • Employee negligence does not bar recovery (with limited exceptions)
  • Faster claims resolution than litigation

Exceptions to No-Fault Recovery

Benefits may be reduced or denied if injury results from:

  • Intoxication - Employee under influence of alcohol or drugs
  • Willful misconduct - Intentional violation of safety rules
  • Horseplay - Reckless behavior unrelated to work
  • Self-inflicted injury - Intentional self-harm
  • Failure to use safety devices - When properly provided and trained

Benefits Not Reduced For:

  • Simple negligence by employee
  • Lack of experience
  • Ordinary workplace accidents
  • Honest mistakes in performing job duties

The Exclusive Remedy Doctrine

What is Exclusive Remedy?

The exclusive remedy doctrine means that workers' compensation is the only remedy an injured employee has against their employer for workplace injuries:

  • Employees cannot sue employers in civil court
  • Protects employers from personal injury lawsuits
  • Trade-off for no-fault benefits
  • Applies to co-employees acting within scope of employment

Exceptions to Exclusive Remedy

Employees may sue outside workers' comp when:

  • Intentional tort by employer - Deliberate injury
  • Third-party liability - Non-employer caused injury
  • Dual capacity - Employer in different legal role
  • Lack of coverage - Employer failed to maintain insurance

Third-Party Liability

When a third party (not the employer) causes workplace injury:

  • Employee receives workers' comp benefits
  • Employee may also sue the third party
  • Insurer may have subrogation rights
  • Common examples: Defective products, negligent drivers, property owners

Exam Tip: Exclusive remedy is a fundamental concept. Employees give up the right to sue their employer in exchange for guaranteed no-fault benefits. This is the "grand bargain" of workers' compensation.
