What is a non-compete agreement?
A non-compete agreement (also known as a covenant not to compete) is a contractual clause or separate contract between an employer and an employee (or contractor) under which the employee agrees, after the end of employment, to refrain from working for a competitor or starting a similar business for a defined period, in a defined geographic area, or in a defined line of business. Paycor+2American Bar Association+2
Key attributes often include:
- Duration: e.g., six months, one year, two years.
- Geographic scope: e.g., same county, state, region, nationwide.
- Scope of activities prohibited: e.g., cannot work for any competitor, or cannot solicit former customers.
- Consideration: What the employee receives in exchange (job offer, promotion, bonus). American Bar Association+1
Employers often use non-competes to protect legitimate business interests such as trade secrets, client goodwill, investment in employee training, proprietary methods, and customer relationships. American Bar Association+1
Why the legality is complicated: one size does not fit all
1. State variation
In the U.S., non-compete agreements are largely governed by state law, not a single federal standard (at least until recent federal activity below). Some states enforce them readily (with reasonableness checks), others heavily restrict or ban them altogether. American Bar Association+2Paycor+2
For example:
- In California, non-compete agreements in employment contracts are largely void under Cal. Bus. & Prof. Code § 16600 and related case law. Federal Trade Commission+1
- States like Colorado, Illinois, Maine and others impose thresholds (salary levels) or other statutory limits. Frost Brown Todd+1
- According to the Economic Innovation Group, four states currently ban non-competes entirely and 34 states plus DC have some form of restriction. Economic Innovation Group+1
2. Contract-law and reasonableness tests
Where non-competes are permitted, courts still typically ask whether the restriction is reasonable in duration, geographic scope and breadth of prohibited activities, and whether it protects a legitimate business interest without imposing undue hardship on the employee or being injurious to the public. American Bar Association+1
3. Recent federal regulations and the shifting legal landscape
In April 2024 the Federal Trade Commission (FTC) issued a rule prohibiting use of non-compete clauses with most workers, declaring them an “unfair method of competition.” Federal Trade Commission+1 However, the rule has been subject to litigation and its full force remains in flux. Orrick+1
4. Practical reality vs theory
Even though non-competes may be legally permitted, enforcement is unpredictable. Some may be overwritten, some only partially enforced, and many may result in negotiation rather than full court action. One recent study noted that despite prevalence, relatively few non-compete disputes end up in court. Federal Reserve Bank of Minneapolis
Recent Research: Why the debate matters
Case-study from the Academics: Innovation impacts
A study from University of New Hampshire found that stricter non-compete enforceability correlates with less valuable innovation output (measured via patent value) across publicly traded firms. The value of patents in states with tighter non-compete enforcement dropped by about 32.5% compared to those with looser enforcement; loosening enforcement led to an increase of ~38.8%. UNH
This suggests non-competes may reduce worker mobility and idea circulation, which can counteract employers’ intended goal of protecting innovation.
Other empirical findings
- The study by UCLA Anderson School of Management (Garmaise, 2009) found that increased enforceability of non-competition agreements reduced executive compensation and R&D spending. UCLA Anderson School of Management
- Another review argues that many commonly-cited empirical studies fail to establish strong causal links between non-competes and reduced innovation—but nonetheless highlight significant error costs and trade-offs. University of Chicago Law Review
Implication for you: Whether you’re an employee or employer, the research tells us that non-competes carry real economic consequences beyond the immediate contract: they affect mobility, innovation, wages, and market dynamics.
Are non-competes legal? A state-by-state snapshot
Here’s a high-level summary table to help you see where things stand. Always check the specific state law and date as legislation changes rapidly.
| State Example | Legal Status of Non-Competes | Key Points |
|---|---|---|
| California (CA) | Generally void for employment contracts | Cal. Bus. & Prof. Code § 16600; case law broadly prohibits non-competes against employees. Federal Trade Commission+1 |
| Colorado (CO) | Allowed only for employees earning above a certain salary threshold; others cannot be bound | E.g., required salary level ~$112,500 (per 2022 statute) or higher for enforceability. Frost Brown Todd+1 |
| Illinois (IL) | Enforceable if ancillary to valid employment contract and reasonable | Must protect legitimate business interest, not impose undue hardship, etc. American Bar Association |
| States with bans or heavy restrictions | 4 states ban entirely; 34+ states have restrictions | See map/tracker from Economic Innovation Group. Economic Innovation Group |
Action point for employees: If you’re asked to sign a non-compete, first check:
- What state’s law applies?
- Is the salary threshold met?
- Does the agreement properly define duration, geography, scope, and legitimate business interest?
- Did you receive something (consideration) when signing?
Action point for employers: If you’re drafting or enforcing a non-compete:
- Make state-law compliance a priority.
- Tailor the agreement to protect specific business interests.
- Keep the restriction as narrow as necessary (duration, geography, role).
- Consider alternative protections (trade secret agreements, non-solicitation agreements) especially in states limiting non-competes.
Recent federal regulatory changes & what they mean
The FTC’s Non-Compete Clause Rule
- The FTC claims ~20-30% of U.S. workers are bound by non-compete clauses. Federal Trade Commission+1
- In April 2024, the FTC issued a final rule declaring non-competes an unfair method of competition, banning new non-compete agreements and rendering many existing ones unenforceable for non-senior executives. Tulane+1
- The rule defines “senior executive” as someone earning more than ~$151,164 and in a policy-making position. Non-competes for senior executives may still be enforceable. Federal Trade Commission
- However, legal challenges have been filed; a federal court in Texas vacated the rule in August 2024 on grounds that the FTC lacked authority. F London
What does this mean in practice?
- Until full clarity emerges from litigation, non-compete enforceability remains uncertain.
- Employers should monitor whether the FTC rule is ultimately upheld nationally or if states take their own approach.
- Employees covered by pre-existing non-compete agreements should review whether their state law restrictions or the impending rule apply.
Why this matters
From a policy perspective, the FTC argues that non-competes suppress wages, restrain job mobility, reduce innovation and entrepreneurship. Federal Trade Commission+1 For employees, this could mean greater freedom to change jobs; for employers, it means rethinking how to protect competitive interests.
What makes a non-compete likely enforceable? (and what raises red flags)
Key factors that courts commonly examine
- Consideration: Did the employee receive something of value in exchange for signing? For new hires, the job itself may suffice; for existing employees, a promotion or bonus may be required. American Bar Association
- Legitimate business interest: Does the employer have a protectable interest (trade secrets, client lists, unique training) that justifies the restriction?
- Reasonableness of scope: Is the duration reasonable (e.g., six months to one year often reasonable; multi-year may be excessive)? Is the geographic scope limited to the area where the employer actually does business?
- Undue hardship on employee: Will the restriction prevent the employee from finding any work or imposing too heavy a burden?
- Public interest: Does enforcing the non-compete harm the public (e.g., limit services, reduce competition)?
- State statutory compliance: Does the state statute require certain thresholds (salary, seniority) or prohibit non-competes for certain classes of employees?
Red flags that suggest weak enforceability
- Broad geographic scope (e.g., “anywhere in the world”) when the employer only operates in one state.
- Long durations (multiple years) with no justification.
- Lack of consideration (employee signed after long employment with no new benefits).
- Employee earning below the threshold (if state law sets one) but required to sign anyway.
- No clear business interest defined, or overly broad prohibition (e.g., “cannot work in any business whatsoever”).
- The state prohibits or heavily limits non-competes for the employee’s role (e.g., low-wage workers).
Practical tips for employees
- Read the agreement carefully: Identify the duration, geographic scope, what “competition” means, what work is prohibited.
- Ask questions: What happens if I move out of state? How does the clause define “competing business”? Is there compensation (or previously promised) for signing?
- Check your state law: If you live in or will move to a state that bans or limits non-competes, you may have additional protections.
- Negotiate: If you haven’t yet signed, you might ask for narrower scope, shorter duration, or even removal of the clause.
- Get professional advice: Consider hiring an employment attorney in your state before signing or if you believe you’re bound unfairly.
- If you’re already under one: Ask: How enforceable is it under your state law? What is the employer’s interest? What is the geographic/duration scope? Could you negotiate a release or buy-out?
- Keep documentation: Save a copy of the agreement, note the date you signed, any other documents (promotions, bonuses) that relate to the agreement.
Practical tips for employers
- Audit existing non-compete agreements: Ensure they comply with each applicable state’s law (especially in multistate operations). Legislation is changing quickly. tradesecretsandemployeemobility.com
- Be clear and specific: Define the business interest, value of training, and what competitive activities will be restricted.
- Calibrate scope: Use duration and geographic scope only as necessary. Avoid overly broad terms.
- Offer good consideration: For existing employees, use promotion, special training access, or bonus when asking them to sign a new non-compete.
- Consider alternatives: Non-solicitation agreements, confidentiality/trade-secret protections, garden-leave clauses might provide protection without broad non-compete constraints.
- Stay alert to federal developments: If the FTC’s rule becomes fully effective, many non-competes may be unenforceable. Have alternative strategies ready.
- Integration clause and severability: Include language that if a portion is deemed unenforceable, the rest remains valid. This offers flexibility if courts “blue-pencil” (modify) the clause rather than void it entirely.
Frequently Asked Questions (FAQs)
Q: I signed a non-compete, but I’m moving to a different state. Does it still apply?
A: Possibly. The agreement usually includes a choice-of-law or venue clause (which state’s law applies, which court). Whether it is enforceable depends on the state whose law governs and where you plan to work. If you move to a state that bans or restricts non-competes, you may have a stronger position—but it’s not automatic.
Q: My employer wants me to sign a non-compete after I’ve been working there a year. Is that valid?
A: It might be, but many states require new consideration for post-employment non-competes (such as a promotion or bonus). If you signed it with no new benefit, it may be unenforceable—or at least vulnerable. Always check your state law.
Q: What if the employer laid me off? Does the non-compete still apply?
A: Many non-competes remain enforceable even if you were terminated, unless the contract says otherwise or state law provides protections for wrongful termination. A non-compete may be easier to challenge if you were fired without cause. For example, some states consider the terminated employee did not receive valid consideration. Legal advice is recommended. Katz Melinger PLLC
Q: I’m starting a business in a totally different line of work. Does the non-compete apply?
A: Possibly not. If the non-compete restricts only work in a defined competing business or field, and your new business is unrelated, you may be outside the scope. However, care must be taken: the definition of “competing business” could be broad.
Q: Are there states where non-competes are illegal?
A: Yes. For example, California broadly voids non-competes for employees. Also, some states completely ban them or restrict them severely. Paycor
Q: Should I refuse to sign a non-compete?
A: It depends. If the non-compete is narrowly tailored and reasonable, it may be accepted. If it is overly broad, covers you broadly, restricts you significantly, or you receive no compensation, you may want to negotiate or refuse. Evaluate based on your mobility, industry, future plans, and legal advice.
Q: What does recent research say about non-competes? Should I be worried if I sign one?
A: Research from the University of New Hampshire found that stringent enforceability of non-competes reduced innovation and worker mobility. UNH Other research found that enforceability may reduce executive compensation, R&D spending, and the value of innovative output. UCLA Anderson School of Management+1 So yes, you should treat the agreement seriously and understand its implications on your career mobility and earnings.
Q: My employer is in one state; I’m moving to another with different rules. Which law applies?
A: Often the contract includes a choice-of-law clause saying which state’s law governs. However, courts may refuse to enforce that clause if it violates the public policy of the employee’s state or imposes undue hardship. The situation is nuanced—get local legal advice.
Key Takeaways for Your Next Steps
- If you are about to sign a non-compete: read carefully, ask for narrower terms, ensure you receive something in exchange, and check your state’s law.
- If you are subject to a non-compete already: review the scope, duration, geographic limits, and ask whether your new role would violate it; consider negotiation or legal review.
- If you are an employer: reassess your non-compete strategy in light of state statutes and federal developments; consider alternatives or more narrowly tailored agreements; keep documentation of consideration and business interest.
- Keep an eye on legal changes: state legislatures and courts are actively revising non-compete enforceability. For example, salary thresholds, bans for certain industries, or outright prohibition may apply soon.
- Balance the company’s interest in protecting trade secrets and the worker’s interest in mobility. Overbroad restrictions can be both unenforceable and harmful to your employer-employee relationship.
