The Clause That Follows You to Your Next Job
Non compete agreements bind an employee after employment ends, restricting where they may work next. They were built for executives with genuine access to secrets and now appear in contracts for sandwich makers and warehouse staff.
A Contract That Operates After the Job Ends
A non compete agreement is a term in an employment contract under which the employee agrees not to work for a competitor, or start a competing business, for a defined period within a defined geography after leaving.
It is distinct from several clauses it gets grouped with. A non disclosure agreement protects specific confidential information and does not restrict where you work. A non solicitation clause prevents poaching clients or colleagues. Only the non compete restricts the ability to practice your occupation at all, which is why it is the one that raises the hardest questions.
The Case For Them
The employer argument is genuine and should be stated at full strength. A firm that invests heavily in training an employee, or that exposes an employee to customer relationships, pricing strategy, or unpatented technical know how, faces a holdup problem. A competitor can hire that employee and obtain the investment without having paid for it.
If firms cannot protect against that, the prediction is that they underinvest in training and share less information internally. Trade secret law offers partial protection, but proving that a departing employee used confidential information is difficult and slow, while a non compete is enforceable on its face.
For a senior executive, a research scientist, or a salesperson holding the entire customer relationship, this argument carries real weight.
Where the Argument Stops Working
The problem is scope. Surveys have consistently found non competes in a substantial share of contracts for low wage workers with no access to secrets and no employer funded training. Reported cases have involved fast food staff, warehouse workers, hair stylists, and camp counselors.
For those roles the protective rationale is absent, and what remains is a restriction on the ability to accept a better offer nearby. That is not protecting an investment. It is reducing the outside options of the worker.
| Worker Type | Employer Investment at Risk | Effect of the Clause |
|---|---|---|
| Senior executive | Strategy, relationships, know how | Plausible protection |
| Research scientist | Unpatented technical knowledge | Plausible protection |
| Retail or food service worker | Minimal | Suppresses outside offers |
Why Wages Are the Real Question
Most workers do not get raises by asking. They get raises by receiving a competing offer, or by moving. Job to job mobility is the primary mechanism through which wage growth occurs in a labor market, and it functions best when workers can credibly threaten to leave.
A non compete removes that threat within the industry where the worker skills are worth most. Research exploiting variation in state enforceability has generally found that stricter enforcement is associated with lower wage growth and reduced job mobility, and that the effects extend to workers who never signed one, because a market with many bound workers has fewer competing offers circulating for everybody.
The most striking finding in this literature is the spillover. A non compete restricts the person who signed it, and it also thins out the market for people who did not, because the offers that would have created competition never get made.
The Entrepreneurship Channel
A second effect operates on business formation. A large share of new firms are founded by people leaving an incumbent in the same industry, since that is where the founder knows the customers, the suppliers, and the unmet need.
Non competes block exactly that path. Comparisons across jurisdictions with differing enforceability, most famously the contrast between California, which has refused to enforce employee non competes for well over a century, and states enforcing them vigorously, have been used to argue that non enforcement contributed to regional dynamism in technology by allowing engineers to leave and start firms. The comparison is suggestive rather than conclusive, since many things differ between those regions, but the mechanism is plausible and the direction is consistent.
A Patchwork Moving Toward Restriction
The law here is state law and it varies substantially. Some states refuse enforcement outright. Many apply a reasonableness test weighing duration, geographic scope, and whether a legitimate business interest is protected. A growing number have enacted wage thresholds below which non competes are void, which targets the low wage abuse directly while leaving executive agreements intact.
At the federal level the Federal Trade Commission finalized a rule in 2024 that would have banned most non competes nationally, treating them as an unfair method of competition. It was challenged immediately and blocked by a federal court before taking effect, and the resulting legal question about the scope of the agency rulemaking authority is broader than non competes themselves. The practical position remains that this is governed state by state, with the direction of travel toward wage thresholds rather than outright bans.
What a Worker Should Actually Know
Three things. Enforceability depends on your state, not on how the document is worded, and some clauses are void regardless of signature. Reasonableness in duration and geography matters, so a one year restriction within a metropolitan area is far more likely to hold than a five year national one. And the practical question is often whether the former employer will bother to litigate, which for a low wage role is usually no, but the chilling effect of the clause operates whether or not anyone sues.
The Bottom Line
Non competes solve a real problem for a narrow set of roles and function as a wage suppression device across a much wider set. The evidence on mobility and wage growth is reasonably consistent, the spillover onto workers who never signed one is the most underappreciated part, and the reform with the clearest logic is a wage or seniority threshold that preserves the protective use while removing the abusive one. That is roughly where state legislatures have been converging, one at a time.
