Missouri At-Will Employment Exceptions: When Can You Sue for Wrongful Termination?

Losing a job is a deeply stressful experience, especially when you know you were fired for doing the right thing. In Missouri, employers frequently use the 'at-will' employment rule to terminate workers without warning. Because of this, many workers mistakenly believe they have absolutely no legal rights when they are fired unjustly. While Missouri is an employer-friendly state, the law strictly protects employees who refuse to break the law or who blow the whistle on illegal corporate behavior.

This article explains the fundamental at-will employment doctrine in Missouri and its most critical common law exceptions. We will explore the public policy exception, implied contracts, and the covenant of good faith and fair dealing.

Understanding the At-Will Employment Doctrine

Missouri is an 'at-will' employment state. This means that, in the absence of a specific employment contract or union agreement, your employer can fire you at any time, for any reason, or for no reason at all. They can fire you because they do not like your personality, because business is slow, or simply because they want to hire someone else. However, 'any reason' does not mean an 'illegal reason.' Employers cannot terminate you based on race, gender, religion, or disability under Mo. Rev. Stat. § 213.055. Furthermore, Missouri courts have carved out specific 'common law' exceptions to the at-will rule.

The Public Policy Exception

The most powerful exception to at-will employment in Missouri is the public policy exception. The state courts have determined that an employer cannot fire you if the termination violates clearly established public policy. This generally falls into two distinct categories.

Refusing to Violate the Law (The Boyle Standard)

If your boss orders you to commit a crime or violate a state regulation, and you are fired for refusing, you have a strong wrongful termination case. This was established in the landmark case Boyle v. Vista Eyewear, Inc., 700 S.W.2d 859 (MO Court of Appeals 1985). In this case, an employee was fired for refusing to manipulate medical eyewear testing. The court ruled that employers cannot force workers to choose between keeping their jobs and breaking the law. Whether it is refusing to dump toxic waste, refusing to commit tax fraud, or refusing to lie to safety inspectors, you are protected.

Whistleblowing to Government Agencies

You are also protected if you report your employer's illegal actions to a government agency or law enforcement. Under Missouri's Whistleblower's Protection Act, Mo. Rev. Stat. § 285.575, the legislature codified protections for private-sector whistleblowers as an exclusive statutory remedy. To prevail, a worker must prove that reporting the unlawful act was 'the motivating factor' behind the employer's decision to discharge them. If you report safety violations to OSHA or financial crimes to the SEC, your employer cannot legally fire you in retaliation.

Implied Contracts and Employee Handbooks

While most Missouri workers do not have a formal employment contract, sometimes an 'implied contract' is created. If your employee handbook explicitly states that you will only be fired for 'just cause' and outlines a mandatory progressive discipline policy (like three warnings before termination), a court might rule that the handbook created an implied contract. If the employer ignores their own written policies and fires you on the spot, you may have grounds for a lawsuit. However, most modern handbooks contain disclaimers stating they are not contracts.

The Covenant of Good Faith and Fair Dealing

While some jurisdictions recognize an implied covenant of good faith and fair dealing as an exception to at-will employment, Missouri courts have firmly rejected this theory. Under established case law such as Neighbors v. Kirksville College of Osteopathic Medicine, 694 S.W.2d 822 (MO Court of Appeals 1985) and Bishop & Assocs., LLC v. Ameren Corp., 520 S.W.3d 463 (MO Supreme Court 2017), an at-will employee cannot sue for wrongful discharge based on a breach of good faith. While an unpaid worker may file a breach of contract or statutory wage claim to recover earned bonuses or commissions, it does not create a tort claim for wrongful termination.

Step-by-Step Process to File a Claim

Wrongful termination cases require a strategic approach. Here is what you must do if you live in St. Louis, Kansas City, or Springfield.

Step 1: Secure Your Evidence

Before you lose access to your company email, save copies of positive performance reviews, disciplinary records, and any emails where you refused to perform an illegal act. Never steal confidential company data, but preserve any evidence that proves the true reason for your firing.

Step 2: File a Charge of Discrimination (If Applicable)

If your firing was tied to discrimination or retaliation for reporting discrimination, you must first file a complaint with the state. You will submit Form MCHR-27, Missouri, Missouri Commission on Human Rights, Charge of Discrimination to the Missouri Commission on Human Rights, Jefferson City or the Missouri Commission on Human Rights, St. Louis. You must do this within 180 days of being fired.

Step 3: File a State Lawsuit

If your claim is based strictly on the public policy exception (the Boyle standard), you can often bypass the MCHR and file a lawsuit directly in state court. Your lawyer will draft a petition and file it in a venue like the Jackson County Circuit Court, Kansas City or the St. Louis City Circuit Court, St. Louis.

How Much Does it Cost in Missouri?

Fighting a corporation can be expensive, but most employment lawyers work to make it accessible for wrongfully terminated workers.

How Long Does the Process Take?

Employment lawsuits are notoriously slow. If you must go through the MCHR, the agency investigation can take 6 to 12 months before you receive a Right to Sue letter. Once a lawsuit is filed in Missouri state court, the discovery phase, depositions, and pre-trial motions typically take 12 to 24 months before you ever reach a jury trial. However, many cases settle out of court within 8 to 14 months if the evidence of retaliation is overwhelming.
