At-will Employment in Missouri: what you need to know
Missouri is an at-will employment state that recognizes the public policy exception. Missouri is at-will and recognizes only the public policy exception. Missouri courts have rejected the implied contract exception based on employee handbooks and have not recognized the good faith covenant. While at-will employment means your employer can generally terminate you at any time without cause, these exceptions provide important protections in specific circumstances.
The public policy exception in Missouri means your employer cannot fire you for reasons that violate a clear public policy. This typically includes termination for refusing to perform an illegal act, exercising a legal right (such as filing a workers' compensation claim or voting), reporting illegal activity (whistleblowing), or performing a public obligation like jury duty. If you believe you were fired for one of these reasons, you may have a wrongful termination claim.
Understanding at-will employment in Missouri is important because it affects your rights in nearly every aspect of the employment relationship. Even in an at-will state, your employer cannot fire you for illegal reasons, such as discrimination based on race, sex, age, disability, or other protected characteristics. Federal laws like Title VII, the ADA, and the ADEA apply in Missouri regardless of the at-will doctrine. If you believe you were terminated for a discriminatory reason, that is a separate legal claim from the at-will analysis.
At-will employment is often misunderstood. Many workers believe it means their employer can do anything, including fire them for illegal reasons. That is not true. Even in at-will states, federal and state anti-discrimination laws prohibit termination based on race, sex, age, disability, religion, national origin, and other protected characteristics. Retaliation for exercising legal rights, such as filing a safety complaint or requesting FMLA leave, is also illegal regardless of at-will status.
One practical step for workers in at-will states is to keep records of your employment. Save performance reviews, commendation emails, and any written communications that document your contributions. If you are ever terminated and believe the real reason was illegal, this documentation can help establish that the stated reason for termination was pretextual. The stronger the evidence of your good performance, the harder it is for an employer to credibly claim a legitimate business reason for firing you.
