Massachusetts WARN Act: Notice, Exceptions, and Penalties

The Massachusetts WARN Act obligation is really two laws working together: the federal Worker Adjustment and Retraining Notification Act, which requires covered employers to give 60 days’ written notice before a plant closing or mass layoff, and the Massachusetts Plant Closing Law, which adds reemployment assistance billing and continued health insurance eligibility for displaced workers. If you employ 100 or more full-time workers in Massachusetts, or you’ve just been told your job is going away, both sets of rules apply.

Which Employers and Layoffs Are Covered

The federal WARN Act reaches any business with 100 or more full-time workers, or 100 or more employees who together work at least 4,000 hours a week excluding overtime.¹ Part-time employees don’t count toward the threshold. A worker is part-time for this purpose if they average fewer than 20 hours a week or have been on the payroll for fewer than 6 of the 12 months before notice would be due.

Two events trigger the 60-day notice:

A plant closing that causes job losses for 50 or more employees at a single site.
A mass layoff affecting 500 or more workers at a single site, or affecting 50 to 499 workers who make up at least one-third of the site’s active workforce.

Thresholds are measured over any 90-day period. That window stops employers from splitting a reduction into smaller rounds to stay under the numbers. If separate layoffs within 90 days add up to a covered event, each group of affected workers is entitled to notice.²

What Massachusetts Adds on Top

The Massachusetts Plant Closing Law, codified at M.G.L. c. 151A, §§ 71A through 71H, supplements the federal statute rather than replacing it.³ It focuses on what happens after the state certifies a plant closing or covered partial closing. Affected workers can become eligible for reemployment assistance benefits, and the employer is billed for 100 percent of the amount paid out. Those bills are due within 30 days, and unpaid amounts accrue the same interest and penalties as overdue unemployment contributions.⁴

Section 71G addresses eligibility for continued health insurance benefits during the transition, a protection the federal WARN Act does not directly provide. Any Massachusetts employer facing a large-scale reduction has to think about both the federal notice obligation and the state’s downstream billing and benefits rules.

What Counts as an Employment Loss

Three situations qualify as an employment loss under federal WARN: a termination that isn’t for cause, a voluntary departure, or retirement; a layoff lasting more than six months; or a cut that reduces an employee’s hours by more than 50 percent in each month of any six-month period.² That last category catches an employer who tries to sidestep a formal layoff by slashing everyone’s schedule instead.

One situation that does not count: a business sale where employees keep their jobs with the new owner. Federal regulations treat that as a technical change of employer, not an employment loss, so no notice is required for the transition itself.⁵ The seller remains responsible for any closing or layoff up to and including the sale date; the buyer picks up responsibility after.

What a WARN Notice Must Contain

The required contents depend on who’s receiving the notice. Federal regulations lay out specifics for three audiences.⁶

For a union, notice goes to the chief elected officer of the bargaining unit and includes the site name and address, a company contact, whether the action is expected to be permanent or temporary, the expected date of the first separation and the schedule after that, and the job titles and names of workers currently in affected positions.

For individual employees who aren’t represented by a union, the notice must be in plain language and state whether the action is permanent or temporary, when separations will start, the expected date for that specific employee’s separation, whether bumping rights exist, and a company contact for questions.

For government recipients, separate copies go to the state dislocated-worker unit and the chief elected official of the local municipality. These copies list the site name and address, a company contact, whether the action is permanent or temporary, separation dates, affected job titles with headcounts, bumping rights, and the name and address of each union representing affected workers.

Filing the Notice in Massachusetts

Federal law requires written notice to three parties: the affected employees or their union, the state entity designated for rapid response, and the chief elected official of the local government where the event will occur.⁷ If the employer pays taxes to more than one local government, notice goes to whichever one received the highest tax payment in the prior year.

In Massachusetts, the designated state agency is the MassHire Department of Career Services. Employers email the completed notice as a PDF or Word document to warnnotice@mass.gov. The agency asks that notices not be mailed or faxed.⁸ Templates are available on the MassHire website.

Once the MassHire Rapid Response team receives a filing, it typically contacts the employer to coordinate on-site workshops, job placement help, and connections to training programs for departing workers.⁹ Filing early gives the state time to line those resources up before the first separation.

When Shorter Notice Is Allowed

The 60 days is not absolute. Federal regulations recognize three exceptions, and the employer always bears the burden of proving one applies.

Faltering Company

This exception applies only to plant closings, not mass layoffs. The employer must show it was actively seeking capital or new business before the shutdown, that it reasonably and in good faith believed giving 60 days’ notice would scare off the capital or deal it needed, and that obtaining that capital or business would have let it avoid or postpone the closing.¹⁰ Vague hopes of a turnaround don’t satisfy this.

Unforeseeable Business Circumstances

This covers closings and layoffs caused by events the employer could not reasonably have predicted when the 60-day clock started. The marker is something sudden, dramatic, and outside the employer’s control, such as a major client abruptly canceling a contract or a strike at a critical supplier.¹¹ A gradually declining sales trend does not qualify.

Natural Disaster

Floods, earthquakes, storms, and similar events can excuse the full notice period, but only when the closing or layoff is a direct result of the disaster. A factory destroyed by a hurricane fits; a factory closed because the hurricane disrupted its supply chain is an indirect result, and the employer would need to rely on the unforeseeable-circumstances exception instead.¹¹

Under any of these exceptions, the employer still has to give as much notice as is practicable and include a brief explanation of why the period was shortened.

Penalties for Skipping or Shortening Notice

An employer that fails to give the required notice without qualifying for an exception owes each affected worker back pay for each day of the violation, up to a maximum of 60 days. The daily rate is the higher of the employee’s average regular rate over the previous three years or their final regular rate, plus the value of lost benefits, including medical expenses that would have been covered. The total cannot exceed half the number of days the employee worked for the company.¹²

What’s owed to each worker is reduced by any wages the employer actually paid during the violation period, any voluntary unconditional payments made to the worker, and any payments the employer made on the worker’s behalf to third parties like health insurers or pension plans.¹²

An employer that fails to notify the local government also faces a civil penalty of up to $500 per day of violation, payable to the municipal treasury. That fine is waived entirely if the employer pays every affected employee the full amount owed within three weeks of ordering the shutdown or layoff. Courts can award reasonable attorney fees to the prevailing party, and if an employer proves it acted in good faith with reasonable grounds to believe no violation occurred, the court may reduce the liability.¹²

Severance Agreements and WARN Waivers

Severance offers sometimes include a waiver of WARN claims. These waivers can be enforceable, but only if the employee agrees voluntarily and knowingly, has a real opportunity to think it over and consult a lawyer, and receives something of reasonable value in exchange.¹³ A waiver buried in fine print or presented under pressure is unlikely to hold up.

If you’re offered severance after a layoff where notice was short or missing, the WARN claim is often the most valuable piece of leverage you have. Signing it away for a week or two of extra pay may not make sense when potential back pay runs up to 60 days. Having an employment attorney review the offer before you sign is worth the cost.

How Enforcement Works

The federal WARN Act is enforced through private lawsuits in U.S. District Court. Individual workers, groups of workers, unions, and local governments can all sue an employer they believe violated the notice requirements.¹⁴ There is no administrative complaint process with the Department of Labor; you go directly to court. The statute does not set its own limitations period, so courts generally apply the most analogous state period, which varies.

Massachusetts handles its Plant Closing Law differently. Employers certified as having undergone a plant closing or covered partial closing are billed directly for reemployment assistance benefits paid to former workers, with the state’s unemployment contribution collection tools backing those bills.⁴ That piece runs through MassHire and the unemployment system rather than through private litigation.
