Minnesota WARN Notice: Requirements, Exceptions, and Penalties

Minnesota employers planning a large layoff or facility shutdown must comply with the federal Worker Adjustment and Retraining Notification Act, and the Minnesota WARN Act notice requirements add a state-level reporting step on top. In short: give 60 days’ written notice to affected workers or their union, the state’s dislocated worker unit, and local government, and file employee-level information with the Minnesota Department of Employment and Economic Development (DEED) at the same time.

Which Employers Are Covered

WARN reaches any “business enterprise” that either employs 100 or more full-time workers, or employs 100 or more workers (including part-time) who together log at least 4,000 hours per week, excluding overtime.¹ A part-time worker for this count is one who averages fewer than 20 hours per week or has been on the payroll fewer than six of the last 12 months.² Because the law covers business enterprises, federal, state, and local government bodies providing public services are outside its scope.

A subsidiary that looks small on its own can still be covered if it shares common ownership or centralized personnel decisions with a parent. Courts weigh how much practical independence the local site has when deciding whether to aggregate employees across related entities. If your headcount hovers near 100, clean payroll records matter.

What Triggers the Notice

Two events require WARN notice: a plant closing and a mass layoff.

A plant closing is the permanent or temporary shutdown of a single site, or one or more operating units within a site, that eliminates 50 or more full-time jobs in any 30-day period.¹

A mass layoff is a reduction that is not a full closing but still hits one of two thresholds at a single site in any 30-day period: at least 50 full-time employees who make up at least 33 percent of the active full-time workforce, or at least 500 full-time employees regardless of percentage.¹ The 500-employee trigger is the one employers most often overlook, because it fires without the 33 percent test.

The 90-Day Aggregation Rule

Employers cannot avoid WARN by staggering smaller rounds. Separate layoffs occurring within any 90-day window get added together, and if the combined total crosses the 50- or 500-employee threshold, notice is owed to everyone in the count unless the employer can show each round arose from a genuinely separate and distinct cause.³ Thirty terminations in January plus 25 more in March at the same site can create a retroactive violation for both groups.

Who Gets the Notice and When

Notice must be delivered in writing at least 60 days before the first separation, and it goes to three groups: each union representing affected workers (or each affected employee individually where there is no union), the state’s dislocated worker unit, and the chief elected official of the local government where the losses will occur.⁴ If the losses fall in more than one local jurisdiction, the local notice goes to the government unit where the employer pays the highest taxes.

In Minnesota, the state notice goes to DEED’s Dislocated Worker Program. The state’s sample letter directs employers to copy both the DEED Commissioner and the State Rapid Response Team Supervisor at DEED’s St. Paul office, using WARN.DEED@state.mn.us.⁵ A separate copy goes to the mayor or other chief elected official of the city or county where the site sits. Certified mail creates a paper trail; email to DEED is fastest.

What the Notice Must Say

A compliant notice covers each of the following:

The name and address of the employment site where the closing or layoff will occur.
Whether the job losses are permanent or temporary, and whether the entire plant is closing.
The expected date of the first separation and the schedule of any later rounds.
Job titles, the number of employees in each classification, and anticipated separation dates by unit or department.
Whether senior employees have bumping rights that let them displace junior employees.
The name and contact information for the chief elected officer of each union representing affected workers.
The name and phone number of a company official who can answer follow-up questions.

Minnesota law adds an obligation the federal statute does not. Under Section 116L.976, any employer filing a federal WARN notice must also report the names, addresses, and occupations of every employee who will be terminated to DEED.⁶ That employee-level data lets the Rapid Response team reach workers individually instead of waiting for them to show up asking for help.

A standard letter on company letterhead is fine as long as it covers everything on the checklist. DEED publishes a fill-in sample on its website.⁵

The Three Exceptions to 60 Days

Three narrow exceptions let an employer give shorter notice, and none of them wipe out the obligation. In every case the employer must still give as much notice as is practicable and include a brief written explanation of why 60 days was not possible.⁷ The employer carries the burden of proof.

Faltering Company

This one applies only to plant closings, not mass layoffs. To qualify, the employer must have been actively seeking financing or new business when the 60-day notice would have been due, with a realistic chance of success, in an amount enough to keep the site open for a reasonable period, and must show a good-faith belief that announcing the potential closure would have scared off the money or the customer.⁷ A company with healthy cash or access to capital markets cannot invoke it by pointing at one struggling facility.

Unforeseeable Business Circumstances

This covers closings or layoffs caused by sudden, dramatic, and unexpected events outside the employer’s control that could not have been reasonably predicted when the 60-day clock started.⁸ The abrupt loss of a major contract or a sudden downturn in the company’s market are the usual examples. A slow sales decline that management chose to ignore does not qualify.

Natural Disaster

Shortened notice is allowed when a closing or layoff results directly from a flood, earthquake, drought, storm, or similar disaster. The employer still owes as much warning as circumstances allow and must explain the shortened timeline when the notice goes out.

Penalties for Skipping Notice

An employer that orders a plant closing or mass layoff without proper notice owes each affected worker back pay and benefits for every day of the violation, up to 60 days. Back pay is figured at the higher of the employee’s average regular rate over the last three years or their final regular rate, and benefits include medical expenses that would have been covered under the employer’s plan.⁹ Courts are split on whether “each day” means calendar days or workdays, so exposure varies by jurisdiction.

Failing to notify local government carries a separate civil penalty of up to $500 per day. That penalty goes away if the employer pays each affected worker in full within three weeks of ordering the shutdown or layoff.⁹

Affected workers or their union can sue in federal court, which has discretion to award reasonable attorney fees to the prevailing party.¹⁰ Liability is reduced by any wages actually paid during the violation period and by voluntary, unconditional payments made to affected workers that were not already required by another law, contract, or company policy.⁹

Pay in Lieu of Notice

WARN has no provision letting an employer swap a lump sum for the 60-day notice period, so an employer that pays workers off and sends them home immediately is technically in violation.¹⁰ The workaround works because the remedy for a violation is back pay and benefits for the notice period, and voluntary payments offset that liability dollar for dollar. Pay 60 days of wages and keep benefits running through the window, and a court has nothing left to award. The payment has to be genuinely voluntary; severance already required by a contract or an existing policy cannot be credited against WARN damages.

If You Are Below 100 Employees

Section 116L.976 encourages any employer considering a plant closing, substantial layoff, or relocation out of state to notify DEED, the affected employees, any union, and the local government even when the employer is too small to be covered by federal WARN.⁶ It is voluntary below the federal 100-employee threshold, and the payoff is practical: notifying DEED opens the door to state-funded retraining, job-search help, and unemployment insurance counseling for departing workers.¹¹
