Massachusetts WARN Act: Advance Notice for Mass Layoffs

The federal Worker Adjustment and Retraining Notification Act, known as WARN, sets the advance-notice rules for large layoffs in Massachusetts. It is one of the topics covered in Massachusetts labor laws on wages, hours, and worker rights. This article explains which employers WARN covers, who has to be notified and when, what the notice must say, the narrow exceptions that shorten the notice window, and how the state’s own voluntary plant-closing law fits alongside the federal rule.

When the federal WARN Act applies in Massachusetts

WARN is a federal law, and Massachusetts has not enacted a separate state notice mandate, so the federal thresholds are the ones that matter. The starting question is employer size. Under 29 U.S.C. § 2101, WARN reaches any business that employs 100 or more workers, not counting part-time employees, or 100 or more workers who together log at least 4,000 hours a week excluding overtime. A part-time employee, for this count, is someone who averages fewer than 20 hours a week or who has worked fewer than 6 of the 12 months before notice is due.

A covered employer owes notice only when the layoff is large enough to be a “plant closing” or a “mass layoff” as the statute defines those terms. A plant closing is the permanent or temporary shutdown of a single site, or of one or more operating units within a site, that causes at least 50 employees to lose their jobs during any 30-day period. A mass layoff is a reduction in force that is not a plant closing and that causes an employment loss during any 30-day period for either 500 or more employees, or for at least 50 employees who make up at least 33 percent of the workforce at the site.

An “employment loss” is not limited to a firing. Under 29 U.S.C. § 2101(a)(6) it also covers a layoff lasting more than 6 months and a cut of more than 50 percent in an employee’s hours in each month of any 6-month period. Employers cannot dodge the thresholds by staging the cuts: employment losses at a single site over any 90-day period are added together unless the employer shows the separate rounds had genuinely distinct causes.

Who must receive notice, and how far in advance

The core rule in 29 U.S.C. § 2102 is that a covered employer may not order a plant closing or mass layoff until 60 calendar days after it serves written notice on three separate recipients. The 60 days run to the first separation, not to the announcement.

The three required recipients are set by 29 U.S.C. § 2102(a). Notice must reach each of them for the 60-day clock to count.

1. Notify the affected employees or their union

   Written notice goes to every affected employee, or to the union that represents them if one exists. Affected employees are those who can reasonably be expected to lose their jobs, including workers who lose their positions through bumping. If a union represents the workers, the employer serves the union rather than the individual members.

2. Notify the state rapid response unit

   The employer notifies the state entity that carries out rapid response activities for dislocated workers. In Massachusetts that function sits within the state workforce agency, which uses WARN notices to line up reemployment services, job-search help, and benefits information for the workers who are losing their jobs.

3. Notify the local government

   The employer notifies the chief elected official of the unit of local government where the closing or layoff will happen. If more than one local government could qualify, the statute directs notice to the one that received the highest taxes from the employer for the prior year.

What a WARN notice must contain

A WARN notice cannot be a bare announcement. The Department of Labor regulation at 20 CFR § 639.7 requires the notice to be specific and to draw on the best information available to the employer when it is served. The regulation sets out different content for each recipient.

Notice to workers who have no union must be written in plain language and state whether the action is permanent or temporary, the expected date of the closing or layoff and of the individual’s separation, whether bumping rights exist, and the name and phone number of a company contact. Notice to a union covers similar ground, plus the job titles affected and the names of the workers currently holding those jobs. Notice to the state rapid response unit and the local government identifies the site, the company contact, the expected date of the first separation, the job titles and the number of workers in each, whether bumping rights exist, and the unions involved. An employer may instead send the government recipients a shorter notice with the site, contact, first-separation date, and headcount, so long as it keeps the fuller detail on site and available on request under 20 CFR § 639.7.

Exceptions that can shorten the notice period

The statute allows a shorter notice in three defined situations, and only three, listed in 29 U.S.C. § 2102(b). Each is read narrowly, and the employer that relies on one carries the burden of proving it applies.

The first is the “faltering company” exception, available only for a plant closing: an employer that was actively seeking capital or business that would have let it avoid or postpone the shutdown, and that reasonably believed giving notice would have driven that financing or business away, may give reduced notice. The second is “unforeseeable business circumstances,” which covers a closing or layoff caused by conditions that were not reasonably foreseeable when the notice would otherwise have been due. The third is a natural disaster, such as a flood or earthquake, that directly causes the job losses.

Penalties for skipping WARN notice

WARN has no permit process and no agency that reviews layoffs in advance. The U.S. Department of Labor publishes compliance guides for workers and employers but does not enforce the Act; enforcement runs through private lawsuits in federal district court.

An employer that violates the notice rule is liable under 29 U.S.C. § 2104 to each affected employee for back pay for each day of the violation, plus the value of benefits the worker would have received, including medical costs incurred during the gap. That liability is capped at the length of the violation up to a maximum of 60 days, and in no case more than half the number of days the employee actually worked for the employer. The amount owed is reduced by any wages the employer paid for the violation period and by certain voluntary payments and benefit contributions.

A separate civil penalty applies to the government side of the notice. Under the same section, an employer that fails to notify the local government is subject to a penalty of up to $500 for each day of the violation. That penalty does not apply if the employer pays each affected worker the full amount it owes them within 3 weeks of ordering the shutdown or layoff. A court can reduce an employer’s liability if the employer proves the violation was in good faith and that it reasonably believed it was complying with WARN.

Massachusetts’ own plant-closing law and rapid response

Massachusetts layers a state program on top of the federal rule, but it works through incentives rather than a second mandate. Chapter 151A of the General Laws contains a plant-closing framework in sections 71A through 71G. Under Mass. Gen. Laws ch. 151A, § 71A, “advance notification” is defined as a voluntary written declaration by the employer that a plant closing will occur. The state law reaches a “facility” with 50 or more employees, a lower headcount than the federal 100-employee floor, but the notice it describes is voluntary rather than compulsory.

The state framework ties into reemployment support. Workers affected by a certified plant closing can qualify for extended unemployment benefits and reemployment assistance during an eligibility period that runs from the date of notification, and the state’s rapid response teams work with departing employees on job placement and retraining. Because the state notice is voluntary, a Massachusetts employer that meets the federal thresholds still looks to WARN for its mandatory 60-day obligation, while the state provisions add benefits and services for the workers who are let go.
