Are Non-Competes Enforceable in Wisconsin?

Non-compete agreements are enforceable in Wisconsin, but only when they clear a high bar. Wisconsin Statute 103.465 declares any non-compete that imposes an unreasonable restraint “illegal, void and unenforceable,” and the employer carries the full burden of proving every element of reasonableness.¹ That framework makes Wisconsin one of the harder states for employers to win on, and it gives departing employees real leverage when a restriction overreaches.

The Five-Factor Test Wisconsin Courts Apply

Every non-compete in Wisconsin is measured against the same five requirements. All five must be satisfied:

The restriction is necessary to protect a specific business interest of the employer, not just to shield it from ordinary competition.
The time restriction is reasonable.
The geographic territory is reasonable.
The restriction is not harsh or oppressive to the employee.
The restriction is not contrary to public policy.

Miss on any one of the five and the agreement fails entirely.²

What Counts as a Reasonable Time, Territory, and Scope

Duration

The clock on a non-compete has to match the interest being protected. Courts have generally accepted one year, and restrictions as long as two years have been upheld in some cases. Past that, the agreement starts to look oppressive. The right number depends on the industry, the employee’s role, and how quickly the protected information loses its value.

Geographic Area

The territory needs to track where the employer actually does business or where you had meaningful customer contact. A nationwide ban on a salesperson who covered three Wisconsin counties is the textbook overreach. Restrictions that cover “all customers” with no geographic limit have likewise been found unreasonable.¹

Scope of Activity

The activities you are barred from doing have to connect to your actual former duties or the employer’s specific line of business. Language that forbids working for “any business which is substantially similar to or in competition with” the former employer has been struck down as too broad.¹ A defensible clause names the specific role, function, or customers that are off-limits.

The Employer Has to Show a Real Interest Worth Protecting

Ordinary competition of the kind any stranger could provide is not something an employer can lock down. Wisconsin courts require “special facts” that make the restriction genuinely necessary.¹

The interests courts have recognized include trade secrets, confidential customer lists, established customer relationships, specialized training the employer paid for, proprietary business information, and the goodwill of the business. The thread running through them is that you gained access to something valuable while employed, and using it right away would hand you an unfair advantage.

This is where employers often lose. A warehouse worker or entry-level administrator rarely has access to the kind of confidential information that supports a non-compete. The more specialized and senior the role, the easier it is to show a protectable interest.

Did You Get Anything for Signing?

A non-compete is a contract, and like any contract it needs consideration. If you signed when you were hired, the job itself is the consideration and that question is simple. It gets harder when the agreement shows up after you have been working for a while.

Continued employment by itself is generally not enough consideration unless your employer actually required you to sign to keep the job. One Wisconsin case held that simply staying on, with nothing tied to the agreement, did not make the covenant binding. A later Wisconsin Supreme Court decision then clarified that when an at-will employer forbears from firing you, that forbearance can count as valid consideration.³

The practical read: if your employer told you to sign the non-compete or be terminated and you signed, consideration is probably there. If the document simply landed on your desk one day with no consequence for refusing, the consideration argument is much weaker. A raise, bonus, or promotion tied to the signing strengthens the employer’s position considerably.

Non-Solicitation Clauses Get the Same Scrutiny

A common misconception is that a non-solicitation clause, which restricts contacting former clients or recruiting former coworkers rather than banning work for a competitor outright, is held to a lighter standard. In Wisconsin, it is not.

Wisconsin courts apply Section 103.465 to non-solicitation provisions, including clauses that forbid soliciting, inducing, or encouraging coworkers to leave for a competitor.³ The same five-factor test governs, and an overbroad non-solicitation clause can be invalidated outright just like a non-compete.

Wisconsin’s All-or-Nothing Rule

Here is where Wisconsin parts ways with most of the country. The statute says a covenant imposing an unreasonable restraint “is illegal, void and unenforceable even as to any part of the covenant or performance that would be a reasonable restraint.”¹ If any piece of your non-compete is unreasonable, the whole clause falls.

Many states let judges “blue-pencil” an overbroad agreement, trimming it to something reasonable and enforcing the rest. Wisconsin courts cannot. They will not rewrite a two-year restriction down to one year or shrink a nationwide territory to your actual sales region. The clause stands or falls as drafted.⁴

One nuance matters. If your employment agreement contains several separate restrictive covenants, such as a non-compete, a non-solicitation clause, and a confidentiality clause, Wisconsin courts may treat them as divisible. One failing covenant does not automatically take the others down, as long as they are drafted as distinct, independent provisions. Within any single covenant, though, the all-or-nothing rule still applies.

What Happens If You Leave and Get Sued

If a former employer thinks you are violating an enforceable non-compete, the usual first step is a demand letter. If that does not resolve things, the next move is typically a request for a temporary injunction, meaning a court order telling you to stop the restricted activity while the case proceeds.⁵

Beyond an injunction, an employer can seek actual damages for losses caused by the breach, liquidated damages if the agreement specifies a dollar amount, and separate damages under Wisconsin’s Uniform Trade Secrets Act if the breach also involved misappropriating trade secrets. The stakes are real enough that even if you believe your non-compete is unenforceable, walking into a competing job without having the agreement reviewed is a gamble. A lawyer’s read-through costs far less than defending a lawsuit.

Two Important Boundaries

Business Sales Follow Different Rules

Everything above applies to employment non-competes. If you are selling a business and the buyer wants you to sign a non-compete as part of the deal, courts in Wisconsin and elsewhere are far more willing to enforce broader restrictions. The buyer is paying for goodwill and customer relationships, and immediate competition from the seller would gut what was purchased. Longer durations and wider territories are more likely to hold up. Negotiate those terms during the deal rather than hoping to challenge them later.

There Is No Federal Non-Compete Ban

The FTC announced a rule in April 2024 that would have banned most non-competes nationwide. It never took effect. Federal courts vacated it, the FTC dropped its appeals in September 2025, and the agency formally removed the rule from the Code of Federal Regulations in February 2026.⁶ Non-compete enforceability remains a state-law question, so Wisconsin’s framework under Section 103.465 is the controlling law for Wisconsin employees.

Pending Change for Healthcare Workers

Wisconsin Senate Bill 657, introduced in the 2025–2026 legislative session, would add protections for medical practitioners including physicians, physician assistants, advanced practice nurse prescribers, and psychologists. Under the bill, a non-compete covering a medical practitioner would be automatically unenforceable if it restricted practice for more than 24 consecutive months, or if the employer terminated the practitioner’s employment. The bill has not been enacted as of early 2026. If you work in one of those roles, the law on your agreement could change; for now, Section 103.465 and the five-factor test still govern.
