You were fired. Your employer says they can do that — Missouri is an at-will state, and they do not need a reason. But that is only half the story. While Missouri is indeed an at-will employment state, there are important limits on when and why an employer can terminate you. If your firing violated one of Missouri's recognized exceptions to at-will employment, you may have a wrongful termination claim — and your former employer may owe you significant damages.

What At-Will Employment Actually Means

At-will employment means that, absent a contract or other legal restriction, either the employer or the employee can end the employment relationship at any time, for any reason or no reason at all. Missouri has followed the at-will doctrine since the 19th century, and it remains the default rule for most employment relationships in the state.

But "any reason" does not mean "every reason." Missouri law recognizes that certain termination decisions are so fundamentally unfair — or so contrary to established public policy — that they cannot be permitted even in an at-will system. These exceptions have evolved through decades of Missouri case law and statute, and they provide meaningful protections for employees who are fired for the wrong reasons.

Exception 1: The Public Policy Exception

The most important and most frequently litigated exception to at-will employment in Missouri is the public policy exception. Missouri courts have held that an employer cannot terminate an employee for reasons that violate a clearly established mandate of public policy.

What Qualifies as "Public Policy"

Missouri courts define "public policy" narrowly — it must be derived from a constitutional provision, statute, regulation, or other clear mandate of law. A general sense of unfairness or a belief that the termination was morally wrong is not sufficient. The employee must identify a specific legal principle that the termination violated.

Missouri courts have applied the public policy exception in several well-established categories.

Refusing to perform an illegal act. If your employer directs you to do something illegal — falsify records, violate safety regulations, commit fraud, ignore environmental laws — and fires you for refusing, you have a wrongful termination claim. Missouri courts have consistently held that employees cannot be punished for declining to break the law at their employer's direction.

Exercising a legal right. Missouri employees have the right to file workers' compensation claims when injured on the job, to vote, to serve on jury duty, and to exercise other rights established by law. An employer who terminates an employee for exercising these rights violates public policy. Workers' compensation retaliation claims under RSMo 287.780 are among the most common applications of this principle — Missouri law specifically prohibits employers from retaliating against employees who file or pursue workers' compensation claims.

Reporting illegal conduct. Employees who report their employer's illegal conduct — whether to the employer itself, to a government agency, or to law enforcement — are protected from retaliation under the public policy exception. This protection applies even if the employee turns out to be wrong about the legality of the conduct, as long as the report was made in good faith. Missouri's public policy exception also extends to employees terminated for exercising accrued statutory rights — following the August 2025 repeal of the statewide paid sick leave mandate, firing an employee for using previously accrued leave may still support a wrongful termination claim under this doctrine.

Cooperating with investigations. Employees who cooperate with government investigations or legal proceedings — including providing testimony, producing documents, or responding to subpoenas — cannot be terminated for their cooperation.

Proving a Public Policy Claim

To succeed on a public policy wrongful termination claim in Missouri, the employee must show that the employer's actions violated a clearly established mandate of public policy, that the employee's conduct related to the public policy was the cause of the termination, and that the employee suffered damages. The employer will typically respond by offering a legitimate reason for the termination and arguing that public policy was not the real motivation. The case then turns on whether the employee can demonstrate that the employer's stated reason is pretextual — a cover story for an illegal firing.

Evidence of pretext can include the timing of the termination (fired shortly after engaging in protected activity), inconsistency with how other employees were treated (similarly situated employees who did not engage in protected activity were not fired), statements by supervisors that suggest the real reason for the termination, deviation from the employer's own policies and procedures, and a history of positive performance reviews that undermines the employer's claim of poor performance.

Exception 2: Implied Contract

While Missouri's at-will doctrine is strong, employers can inadvertently create implied employment contracts through their handbooks, policies, and conduct. If an employer's handbook includes a progressive discipline policy (verbal warning, written warning, suspension, termination) without a clear at-will disclaimer, an employee may argue that the handbook created an implied promise that termination would follow the specified procedure.

Missouri courts evaluate implied contract claims by examining the language of the handbook or policy (does it use mandatory language like "will" or "shall" rather than discretionary language like "may"), whether the employee received the handbook and reasonably relied on its terms, whether the handbook includes a clear and conspicuous at-will disclaimer, and the employer's course of conduct (did the employer consistently follow the progressive discipline process).

The implied contract exception is a trap for employers who draft employee handbooks without legal review. A well-drafted handbook includes a prominent at-will disclaimer that is acknowledged in writing by each employee. Without that disclaimer, the handbook's disciplinary procedures can become enforceable promises.

For employees, an implied contract claim can be valuable because it allows you to argue that the employer breached its own promises — regardless of whether the termination was motivated by discrimination or public policy considerations. If the handbook says you will receive three warnings before termination and you were fired without any warnings, the implied contract may give you a claim.

Exception 3: Whistleblower Protections

Missouri provides specific statutory protection for whistleblowers through RSMo 285.575, which prohibits employers from retaliating against employees who report violations of law or regulation to their employer or to a governmental body. This statute codifies the whistleblower aspect of the public policy exception and provides an independent cause of action for employees who are fired for reporting illegal conduct.

What Counts as Protected Whistleblowing

Missouri's whistleblower statute protects employees who report in good faith what they reasonably believe to be a violation of law or regulation. The report can be made internally (to the employee's supervisor, HR department, or compliance officer) or externally (to a government agency, law enforcement, or other governmental body). The employee does not need to be correct that a violation actually occurred — the statute protects good-faith reports of reasonably believed violations.

Federal Whistleblower Statutes

In addition to Missouri's statute, several federal laws provide whistleblower protections in specific industries. The Sarbanes-Oxley Act protects employees of publicly traded companies who report securities fraud, mail fraud, wire fraud, or violations of SEC rules. The False Claims Act protects employees who report fraud against the federal government. OSHA whistleblower provisions protect employees who report workplace safety violations. The Dodd-Frank Act provides protections and financial incentives for individuals who report securities law violations to the SEC.

Each federal statute has its own filing requirements, deadlines, and remedies. An experienced employment attorney can evaluate which whistleblower protections apply to your situation and recommend the most effective approach.

What to Do If You Have Been Wrongfully Terminated

If you believe you have been fired for an illegal reason, the steps you take in the first days and weeks after termination can significantly affect the outcome of your case.

Preserve evidence immediately. Save copies of your personnel file, performance reviews, disciplinary records, emails, text messages, and any other documents related to your employment and termination. If you received a termination letter or separation agreement, keep the original. Do not sign a severance agreement or release of claims without consulting an attorney first — these agreements typically require you to waive your right to sue in exchange for severance pay, and the terms are often negotiable.

Document the circumstances of your termination. Write down everything you remember about the termination — who was present, what was said, the reason given (if any), and the events leading up to the firing. Include dates, times, and names of witnesses. Do this as soon as possible while your memory is fresh.

File for unemployment benefits. You are entitled to unemployment benefits in Missouri if you were terminated without cause, and filing for benefits creates an official record of the employer's stated reason for termination. If the employer contests your benefits and provides a different reason than what they told you, that inconsistency can be powerful evidence in a wrongful termination case.

Consult an employment attorney. Wrongful termination claims are time-sensitive. Depending on the nature of your claim, filing deadlines can be as short as 180 days (for MHRA discrimination claims) or as long as five years (for breach of contract claims). An attorney can evaluate your situation, identify the strongest legal theories, and take immediate steps to preserve your rights.

Do not badmouth your former employer on social media. While it is natural to feel angry, public statements about your termination can be used against you in litigation. Discuss your situation with your attorney and close confidants — not the internet.

Damages in Wrongful Termination Cases

If you succeed on a wrongful termination claim in Missouri, the damages available depend on the legal theory you pursue.

Public policy claims can result in compensatory damages (lost wages, benefits, and emotional distress) and, in egregious cases, punitive damages designed to punish the employer and deter similar conduct.

Implied contract claims typically result in contract damages — the wages and benefits you would have earned had the employer followed its own procedures.

Statutory claims (discrimination, whistleblower retaliation, workers' compensation retaliation) carry their own damages provisions, which may include back pay, front pay, compensatory damages, punitive damages, and attorney fees.

Missouri juries have awarded substantial damages in wrongful termination cases, particularly when the employer's conduct was willful, retaliatory, or involved a pattern of mistreatment. Our firm has secured significant results in employment discrimination cases, and these outcomes reflect the seriousness with which Missouri courts treat retaliatory and wrongful terminations.

Frequently Asked Questions

Can my employer fire me for no reason in Missouri?

Under the at-will doctrine, yes — your employer can terminate you for no reason at all. But they cannot fire you for an illegal reason, including discrimination based on a protected characteristic, retaliation for exercising a legal right, retaliation for reporting illegal conduct, or violation of a clearly established public policy. The distinction between "no reason" and an "illegal reason" is where wrongful termination law operates.

Do I have a wrongful termination claim if my employer did not follow its own policies?

Possibly. If your employer has a progressive discipline policy or other termination procedures documented in an employee handbook, and the handbook does not contain a clear at-will disclaimer, the employer may have created an implied contract to follow those procedures. Terminating you without following the documented process could constitute breach of that implied contract. However, if the handbook includes a clear and conspicuous at-will disclaimer, courts will generally enforce the disclaimer regardless of the handbook's other provisions.

How long do I have to file a wrongful termination lawsuit in Missouri?

The deadline depends on the legal theory. Discrimination claims under the MHRA must be filed with the MCHR within 180 days. Workers' compensation retaliation claims under RSMo 287.780 must be filed within the applicable statute of limitations. Breach of implied contract claims are subject to a five-year statute of limitations. Public policy tort claims are generally subject to a five-year limitations period. Because multiple theories may apply to your situation, consult an attorney as soon as possible to ensure you do not miss any applicable deadline.
