Jessica JohnsonMissouri or California? Your non-compete agreement's fate could not be more different depending on which state's law governs it. Missouri enforces non-competes that meet a "reasonableness" standard — while California, Minnesota, and several other states have moved to ban them outright. Meanwhile, the Federal Trade Commission's nationwide non-compete ban, finalized in 2024, was blocked by federal courts before taking effect and remains in legal limbo as of 2026.
For Missouri workers signing a non-compete — and for Missouri employers drafting them — understanding where Missouri stands relative to the national landscape is essential before putting pen to paper.
How Missouri Non-Compete Law Works
Missouri has no statute governing non-compete agreements. Courts apply a common-law reasonableness test developed over decades of case law. Under this framework, a non-compete is enforceable if it satisfies four conditions:
- Ancillary to an enforceable agreement — the non-compete must be part of a valid employment contract or business transaction, not a standalone promise
- Adequate consideration — something of value must be exchanged; for new hires, the job itself is sufficient; for existing employees, a promotion, raise, or access to confidential information may constitute consideration
- Legitimate protectable interest — the employer must have a genuine business interest to protect: trade secrets, confidential customer lists, specialized training, or established customer relationships
- Reasonable in scope — the restrictions on geography, duration, and covered activities must be no broader than necessary to protect the legitimate interest
Missouri courts will blue-pencil — modify, not void — a non-compete that is overly broad [Healthcare Servs. of the Ozarks, Inc. v. Copeland, 198 S.W.3d 604 (Mo. 2006)]. This means an employee who signs a non-compete covering the entire United States for five years may find that a Missouri court enforces a narrower version covering only their actual sales territory for 18 months. Blue-penciling makes Missouri more employer-friendly than states that void overly broad agreements in their entirety.
Missouri vs. States That Ban Non-Competes
A growing number of states have moved beyond "reasonableness review" to outright prohibition of most employee non-compete agreements:
| State | Legal Approach |
|---|---|
| California | Complete ban — non-competes are void and unenforceable as a matter of public policy (Cal. Bus. & Prof. Code § 16600) |
| Minnesota | Banned all new non-competes for employees as of January 1, 2023 |
| North Dakota | Non-competes unenforceable by statute for employees except in limited business sale contexts |
| Oklahoma | Non-competes in employment contracts are void under Okla. Stat. tit. 15, § 219A |
| Missouri | Enforceable if "reasonable" — no ban |
What this means for interstate workers: If a Missouri employee who signed a non-compete moves to California and begins working for a competitor, the California employer may be protected under California law. California courts routinely refuse to enforce non-competes — even under choice-of-law clauses selecting Missouri law — if enforcing them would require a California-based employee to leave their job. The Florida Non-Compete Agreements guide shows how a state at the opposite end of the spectrum (Florida actively encourages non-compete enforcement by statute) approaches the same issue.
Missouri vs. States With Protective Non-Compete Statutes
Some states — including Illinois, Nevada, and Washington — have not banned non-competes but have enacted statutes adding protections that Missouri's common law does not provide:
Illinois (EFAA, 2022):
- Non-competes are void for employees earning less than $75,000/year
- Non-solicitation agreements void for employees earning less than $45,000/year
- Employers must provide a 14-day review period and advise employees to seek counsel
Nevada:
- Non-competes must be supported by additional consideration beyond continued employment for existing employees
- Courts must blue-pencil rather than void agreements that are partially enforceable
Missouri, by comparison:
- No income threshold — a $20,000/year warehouse worker could theoretically be bound by a non-compete
- No mandatory review period before signing
- No requirement to advise the employee to consult an attorney
- Blue-penciling available, but there is no statutory floor
Missouri workers — particularly lower-wage employees — receive fewer protections from non-competes than workers in states with income-based thresholds. A Missouri warehouse employee asked to sign a non-compete as a condition of employment has no statutory right to refuse and no minimum salary protection.
The FTC's Blocked Non-Compete Rule
In April 2024, the Federal Trade Commission issued a final rule that would have banned virtually all new non-compete agreements with employees nationwide and made most existing non-competes unenforceable. The rule was challenged immediately in federal court and was enjoined (blocked) by the U.S. District Court for the Northern District of Texas before its effective date of September 4, 2024. The FTC appealed; as of mid-2026, the rule remains blocked and its ultimate fate depends on pending litigation and potential Supreme Court review.
What this means for Missouri workers and employers in 2026:
- The FTC rule is NOT in effect — Missouri non-competes remain governed by state common law
- Employers may continue to use non-competes that meet Missouri's reasonableness standard
- Employees cannot invoke the FTC rule as a defense to a Missouri non-compete
- If the FTC rule is eventually upheld on appeal, it will dramatically change Missouri's landscape — employers and employees should monitor developments
The Maryland Non-Compete Agreements guide covers a state that enacted its own non-compete income threshold even before the FTC rule, illustrating the state-level legislative trend that may ultimately reach Missouri regardless of the federal outcome.
Employee vs. Employer Strategy in Missouri Non-Compete Disputes
If you are an employee asked to sign a non-compete:
- Read the geographic scope, duration, and covered activities carefully — courts will enforce reasonable terms
- Ask your employer what specific protectable interest justifies the restriction
- Request a narrower agreement: a 1-year restriction in your sales territory is far more defensible than a 3-year national ban
- Consider whether the role gives you genuine access to trade secrets or key customer relationships — if not, the employer may struggle to prove a protectable interest
If you are an employer drafting a non-compete:
- Tailor the agreement to the specific employee's role and the specific interest you are protecting — generic company-wide templates are the most vulnerable to blue-penciling
- Document the consideration clearly (sign-on bonus, access to customer list, specialized training)
- Restrict geography to the area where the employee actually worked with customers or clients
- Limit duration to the minimum necessary (18 months is typically more enforceable than 3 years in Missouri courts)
- Use non-solicitation clauses (restrictions on poaching clients or coworkers) as a complementary tool: Missouri courts enforce reasonable non-solicitation agreements under the same reasonableness standard, and they are often easier to justify than a full non-compete
- Review agreements annually as your employee's role evolves — an agreement signed for a junior sales rep may not be appropriate when that person is promoted to regional director with access to broader confidential data
New Jersey Non-Compete Agreements comparison note: New Jersey has not enacted a comprehensive non-compete statute, but pending legislation would create income thresholds similar to Illinois. Missouri employers with multi-state operations should draft state-specific provisions rather than relying on a single Missouri choice-of-law clause, as that clause may not survive judicial scrutiny in states with stronger employee protections.
Key takeaway: Missouri sits in the middle of the national non-compete spectrum — it enforces reasonable agreements but gives courts power to narrow excessive ones. The FTC's nationwide ban remains blocked and inapplicable in Missouri as of 2026. Workers in lower-wage positions are particularly exposed, as Missouri lacks the income-based exemptions that other states have enacted. Both sides of the negotiating table benefit from advice from a Missouri employment attorney before signing or enforcing a non-compete.
