How should a Minnesota employer protect confidential business information when employees have access to trade secrets, client data, and proprietary processes? A confidentiality agreement (also called a non-disclosure agreement or NDA) is the primary contractual tool for preventing unauthorized disclosure. Since Minnesota voided non-compete clauses in employment agreements in 2023, confidentiality agreements have become even more critical for employers who need to protect sensitive information without restricting where former employees can work. For broader context, see Minnesota Employment Law for Employers.
What Makes a Minnesota Confidentiality Agreement Enforceable?
Minnesota courts enforce confidentiality agreements that are reasonable in scope, supported by adequate consideration, and consistent with public policy. The threshold question is whether the agreement clearly defines what it protects. Vague references to “all company information” invite judicial skepticism; specific categories (customer lists, pricing models, product formulas, source code) demonstrate that the employer has identified genuinely protectable interests.
Consideration is the second requirement. When a confidentiality agreement is signed at hiring, the employment itself provides adequate consideration. For existing employees, Minnesota courts require independent consideration: a promotion, bonus, stock grant, or access to new categories of confidential information. An employment agreement that bundles the confidentiality obligation with other terms at the outset avoids this issue entirely.
Duration matters as well. For information that qualifies as a trade secret under the Minnesota Uniform Trade Secrets Act (Minn. Stat. ch. 325C), the obligation can last as long as the information retains trade secret status. For other confidential information, courts expect a reasonable time limit. I typically draft two tiers: an indefinite obligation for trade secrets and a defined term (two to five years) for broader confidential information categories.
What Information Qualifies as a Trade Secret Under Minnesota Law?
The Minnesota Uniform Trade Secrets Act defines a trade secret as “information, including a formula, pattern, compilation, program, device, method, technique, or process” that derives economic value from secrecy and is the subject of reasonable efforts to maintain that secrecy (Minn. Stat. § 325C.01, subd. 5). Both elements must be satisfied: the information must have value because it is secret, and the employer must take affirmative steps to keep it that way.
The “reasonable efforts” requirement is where many employers fail. Storing trade secrets on an unsecured shared drive, sharing them with employees who have no need to access them, or failing to mark documents as confidential all undermine a later claim that the information was protected. I advise employers to implement access controls, require confidentiality agreements before granting access, and maintain an internal register of what the company considers trade secret information.
The federal Defend Trade Secrets Act provides a parallel layer of protection and allows employers to bring misappropriation claims in federal court. It also includes a whistleblower immunity provision that employers must disclose in any confidentiality agreement: employees who disclose trade secrets to a government official or attorney for purposes of reporting a suspected violation of law are immune from liability. Failing to include this notice forfeits the employer’s right to seek exemplary damages or attorney fees in a DTSA action.
How Should Employers Structure Confidentiality Obligations for Different Roles?
Not every employee needs the same level of confidentiality protection. A software engineer with access to source code and product roadmaps presents different risks than a warehouse worker who never sees proprietary data. Tailoring the agreement to the role makes it more enforceable and reduces the perception that the employer is imposing blanket restrictions without genuine business justification.
For executives and senior managers, I draft comprehensive agreements covering strategic plans, financial projections, M&A discussions, and board-level deliberations. These agreements typically include non-solicitation provisions (which remain enforceable after Minnesota’s non-compete ban) and require the return or certified destruction of all confidential materials at termination. For technical employees, the focus shifts to intellectual property assignment, source code protection, and restrictions on taking confidential information to a competitor. For client-facing roles, customer lists, pricing terms, and relationship data are the priority.
Regardless of role, every confidentiality agreement should specify what the employee must do at separation: return all devices and documents, delete copies from personal accounts, and certify compliance in writing. The exit checklist is not just good practice; it creates a documentary record that strengthens the employer’s position if a dispute arises later.
What Happens When an Employee Breaches a Confidentiality Agreement?
When a breach occurs, speed matters. The Minnesota Uniform Trade Secrets Act authorizes injunctive relief: “Actual or threatened misappropriation may be enjoined” (Minn. Stat. § 325C.02). A temporary restraining order can prevent further disclosure within days of discovering the breach. Waiting too long to act can undermine the employer’s claim that the information was truly confidential, since delay suggests the harm was not urgent.
Beyond injunctive relief, employers can recover actual damages for the economic loss caused by the breach, plus unjust enrichment if the breaching party profited from the disclosure. For willful and malicious misappropriation, the court may award exemplary damages up to twice the actual damages, plus attorney fees (Minn. Stat. § 325C.04). These remedies create meaningful deterrence, but only if the employer can prove what was taken and how it was used.
I advise employers to build their enforcement capability before a breach happens. That means maintaining access logs, using data loss prevention tools, and conducting exit interviews that put departing employees on notice. When litigation becomes necessary, these records form the evidentiary foundation for both the injunction and the damages claim.
How Do Confidentiality Agreements Interact with Minnesota’s Non-Compete Ban?
The 2023 non-compete ban under Minn. Stat. § 181.988 explicitly preserves confidentiality agreements. The statute defines “covenant not to compete” and then carves out “a nondisclosure agreement, or agreement designed to protect trade secrets or confidential information.” This means employers can still contractually prohibit employees from disclosing or using confidential information after employment ends, even though they can no longer restrict where the employee works.
This distinction makes confidentiality agreements the centerpiece of post-employment protection for Minnesota employers. A former employee can accept a position with a direct competitor, but they cannot bring trade secrets, client lists, or proprietary processes with them. The practical challenge is proving that a departing employee used confidential information rather than general skills and knowledge, which is why specificity in the agreement’s definition of protected information matters so much.
Employers who previously relied on non-competes should conduct a full review of their employment agreements and strengthen their confidentiality and non-solicitation provisions. The combination of a well-drafted confidentiality agreement, a non-solicitation clause, and strong internal trade secret protections provides coverage that is, in many cases, more enforceable than the non-competes they replace.
