Missouri Is an At-Will Employment State

In Missouri, most employment relationships are considered at-will. This means an employer can generally end employment at any time, for almost any reason, or no stated reason at all, as long as the reason is not illegal. This surprises many injured workers, since it means simply being on workers’ comp does not, by itself, protect a job.

A workers’ comp claim does not pause the normal rules of employment. An employer can still enforce attendance policies, restructure a department, or eliminate a position while a worker is receiving benefits, as long as the decision is not driven by the claim itself.

The Key Exception: Retaliatory Discharge

Missouri law creates a specific and important exception to at-will employment. Under Missouri Revised Statutes Section 287.780, it is illegal for an employer to discharge or discriminate against an employee because that employee exercised their rights under the workers’ compensation law, including filing a claim, testifying in a workers’ comp proceeding, or simply reporting a work injury.

This is often called a retaliatory discharge claim, and it is treated separately from the underlying workers’ comp case itself. If an employer’s real reason for termination is the claim, rather than a legitimate business reason, that termination can give rise to its own legal claim.

What Employers Can Still Do While a Claim Is Open

A termination that happens while a worker is receiving benefits is not automatically retaliatory. Employers generally retain the ability to:

• Conduct layoffs or reductions in force that affect the entire department or company, not just the injured worker
• Terminate for documented performance or conduct issues that exist independently of the injury
• Determine that no light-duty or modified position is available that fits a worker’s medical restrictions
• End employment when a worker cannot return to any available role, even after accommodation efforts

The key question in each of these situations is whether the stated reason is genuine or a pretext to punish the worker for the claim.

Termination Does Not End Your Workers’ Comp Benefits

One point that causes a lot of confusion: losing your job does not automatically cut off your workers’ comp benefits. Medical treatment, temporary disability payments, and any permanent disability benefits you are entitled to are tied to the injury and the claim, not to your continued employment with that employer. If you are terminated while receiving benefits, confirm that your benefits continue as they should, since some employers or adjusters treat termination as a reason to stop payments when there is no legal basis to do so.

How Workers’ Comp Interacts With FMLA

The Family and Medical Leave Act is a separate law from workers’ compensation, and the two often get confused. FMLA can provide job-protected leave for eligible employees at covered employers, generally for a limited period, but eligibility depends on factors like how long you have worked there and the employer’s size. Missouri workers’ comp law itself does not require an employer to hold a position open indefinitely. This is why timing and documentation matter so much when a worker is trying to determine whether something improper happened.
