Suing Over a Work Injury in Missouri

When Missouri law lets an injured worker sue the employer, suing a third party such as a driver or equipment maker, and what to do if the employer has no workers' comp.

Short answer: A covered employer must pay workers' compensation regardless of fault and is released from all other liability for the injury, and the worker's and family's rights under the law exclude other remedies except rights the law does not provide for. Mo. Rev. Stat. §§287.120.1, .2, 287.280.1

Suing your employerA covered employer must pay workers' compensation regardless of fault and is released from all other liability for the injury, and the worker's and family's rights under the law exclude other remedies except rights the law does not provide for. Co-employees are also released, except when the co-employee committed an affirmative negligent act that purposefully and dangerously caused or increased the risk of injury. If the employer fails to insure as required, the worker may instead sue the employer.

Suing someone other than your employerWhen a third person is liable for the injury or death, the employer is subrogated to the worker's (or dependents') rights against that person. When the worker recovers from the third party, the employer pays its proportionate share of the costs, including a reasonable attorney fee, and the balance is split between employer and worker in the ratio the statute sets (adjusted if the worker is found partly at fault), unless they agree otherwise.
Any notice requirement for the worker's third-party suit was not found in the parts read.
If your employer has no workers' compIf an employer fails to insure as required, the injured worker (or dependents) may choose to sue the employer for damages, and the employer cannot defend on the ground of a co-worker's negligence, assumption of risk, or the worker's own negligence; or claim under the workers' compensation law with payments commuted and immediately payable; or ask the Division to pay medical expenses from the Second Injury Fund. An employer that knowingly fails to insure commits a class A misdemeanor and owes the state a penalty of up to three times the annual premium or up to $50,000, whichever is greater; a repeat violation is a class E felony.
