Wisconsin is one of the most employee-friendly states in the country when it comes to non-compete agreements, thanks to Wisconsin Statute 103.465. Under this statute, a non-compete that is unreasonable in any respect — duration, geography, scope of activity, or supported by inadequate consideration — is void in its entirety. Wisconsin courts do not blue-pencil. They do not rewrite overbroad terms. If any part of the restriction is unreasonable, the entire covenant fails. This all-or-nothing rule creates a significant practical asymmetry. Employers who draft aggressive non-competes risk losing every protection in the agreement, including narrowly-drawn non-solicits and confidentiality terms tied to the covenant. For employees, it means that aggressive drafting often works in your favor: a single overbroad provision can collapse the whole restriction.
What is a Enforceability?
A non-compete agreement in Wisconsin is governed primarily by Wisconsin Statute 103.465, which states that any covenant restricting an employee's competitive activity must be reasonable as to time, territory, and scope, and supported by valuable consideration. The statute applies to non-competes, non-solicits, and certain other restrictive covenants tied to employment. Courts apply the Streiff v. American Family Mutual Insurance Co. and Star Direct, Inc. v. Dal Pra line of cases to assess reasonableness. Unlike most states, Wisconsin courts will not modify or 'blue-pencil' an overbroad covenant — the entire restriction is void if any part is unreasonable.
Red flags to watch for
Wisconsin courts require the geographic scope to be no broader than necessary to protect the employer's legitimate interests. A statewide or multi-state restriction without a corresponding territory of actual business activity is unreasonable and voids the entire covenant under Wis. Stat. 103.465.
Wisconsin courts have routinely struck restrictions longer than 2 years for ordinary employees. Anything over 12 months requires a strong justification tied to specific protectable interests. Overbreadth in duration alone voids the whole covenant.
Vague language like 'similar work' or 'related business' fails the reasonableness test in Wisconsin. The covenant must specifically identify the activities restricted. Star Direct, Inc. v. Dal Pra (2009) makes clear that activity scope must be narrowly drawn.
Wisconsin requires real, valuable consideration. Continued at-will employment is not adequate consideration in Wisconsin for a non-compete signed after hire. A specific benefit — bonus, promotion, stock — must accompany the covenant.
A non-solicit that covers the entire customer base — not just those the employee worked with or learned about — is overbroad under Wisconsin law. The restriction must be tied to the employee's actual activity, not the employer's whole book of business.
Wisconsin's all-or-nothing rule cannot be contracted around. A severability clause cannot give a court the power to rewrite the covenant. If the agreement contains an overbroad term, the entire restriction falls regardless of what the severability clause says.
A covenant that protects entities the employee never worked for is overbroad. Wisconsin courts have voided non-competes that purport to restrict competition with affiliated companies the employee had no relationship with.
Your legal rights
Wisconsin Statute 103.465 is the controlling authority on employment non-competes in Wisconsin. It voids any covenant that is unreasonable as to time, territory, or scope of activity, and the entire covenant fails if any part is unreasonable. Case law including Streiff v. American Family Mutual Insurance Co., 118 Wis. 2d 602 (1984), Star Direct, Inc. v. Dal Pra, 2009 WI 76, and Tatge v. Chambers & Owen, Inc., 219 Wis. 2d 99 (1998) elaborate on the reasonableness test and the rule against judicial reformation. Wisconsin courts will not blue-pencil or rewrite overbroad covenants. The Wisconsin Trade Secret Act (Wis. Stat. 134.90) provides separate protection for trade secrets independent of non-compete enforcement.
Questions to ask before you sign
- 1Does the geographic scope match the actual territory where you did business for this employer?
- 2Is the duration 12 months or less, and if longer, what specific business interest justifies it?
- 3What specific activities are restricted, and are they described with precision rather than vague phrases like 'similar work'?
- 4What valuable consideration — beyond continued employment — was provided for signing this covenant?
- 5Does the non-solicit cover the entire customer base or only customers you actually served?
- 6Does the restriction extend to affiliated companies you never worked for, and is that justified?
- 7Has the employer made any prior attempt to enforce a similar covenant, and what was the result?
