Massachusetts WARN Act: Notice Requirements and Employer Penalties

The Massachusetts WARN Act is a layered framework: the federal Worker Adjustment and Retraining Notification Act requires 60 days’ written notice before a plant closing or mass layoff by employers with 100 or more full-time workers, and a parallel Massachusetts law under General Laws Chapter 151A, Sections 71A through 71G, extends notice obligations and funds reemployment and health insurance benefits for workers at facilities with as few as 50 employees.¹² An employer that misses the notice period owes affected workers back pay and benefits for each day it fell short, up to 60 days, plus a civil penalty of up to $500 per day for failing to notify the local government.³

Which Employers Must Comply

The federal WARN Act covers any business that employs 100 or more full-time workers, or 100 or more employees (including part-time) who together work at least 4,000 hours per week, excluding overtime.¹ A part-time employee under the federal rule is someone who has worked fewer than six of the last 12 months or who averages fewer than 20 hours per week. Part-timers don’t count toward the 100-employee threshold, but once an employer is covered, part-time workers are still entitled to receive notice.³

Massachusetts sets a lower bar. Section 71A applies to any plant, factory, commercial business, hospital, institution, or other workplace in the Commonwealth that had 50 or more employees during any month in the six months before the closing date. The state definition counts both full-time and part-time workers who have received wages for the past four quarterly periods and are otherwise eligible for unemployment benefits. The employer must also have owned or operated the facility for at least one year, and seasonal employers are excluded.²

A business with 50 to 99 employees sits in the state-only zone: no federal WARN obligation, but still subject to Massachusetts notification and benefit rules. A business with 100 or more employees must handle both.

When the 60-Day Notice Is Required

The federal WARN Act covers two triggering events. A plant closing is a permanent or temporary shutdown of a single site, or of one or more operating units within a site, that causes 50 or more full-time employees to lose their jobs during any 30-day period. A mass layoff is a workforce reduction that is not a plant closing and that results in job losses during any 30-day period for either 500 or more full-time employees, or at least 50 full-time employees if they make up at least 33 percent of the active workforce at the site.⁴

The Massachusetts law reaches plant closings and “partial closings.” A plant closing under state law is a permanent decision to cease all operations at a covered facility. A partial closing is a permanent shutdown of a major discrete portion of the business that terminates a significant number of employees and affects workers and communities in a way similar to a full closing. A partial closing only unlocks state benefits once the commissioner certifies it as a “covered partial closing” under Section 71C.²

Temporary layoffs and seasonal workforce changes don’t trigger either framework. These rules target permanent losses.

Massachusetts also requires employers with 50 or more employees to submit WARN notices at least 60 days before a layoff or closing to the MassHire Department of Career Services, which runs rapid response teams for displaced workers.⁵⁶

What the Notice Must Contain and Who Receives It

Under federal law, the employer cannot order a plant closing or mass layoff until 60 days after serving written notice on affected employees (or their union representative), the state dislocated worker unit, and the chief elected official of the local government where the closing will occur.¹ In Massachusetts, the state recipient is the Executive Office of Labor and Workforce Development.⁵

Federal regulations require the notice to state whether the action is permanent or temporary, the expected start date of the closing or layoff, the anticipated date of each individual’s separation (or a 14-day window around it), whether bumping rights exist, and a company contact name and phone number. Unionized employees receive notice through their bargaining representative. Non-union employees must be notified individually.

The state framework defines “advance notification” as a voluntary written declaration from the employer to employees or their union representative that a plant closing will occur. If the employer does not voluntarily announce the closing, the commissioner can independently determine the date of notification, which keeps the state’s benefits machinery running regardless of employer cooperation.²

When Shorter Notice Is Allowed

The federal WARN Act recognizes three narrow situations where fewer than 60 days’ notice is permitted. In every case, the employer must still give as much notice as possible and must explain in writing why the period was shortened. The employer carries the burden of proving the exception applies, and relying on one without strong facts leaves the employer exposed to the same penalties as giving no notice at all.

Faltering company. This applies only to plant closings. The employer must have been actively seeking new capital or business, must have reasonably believed that giving notice would scare off that capital, and must show the funding would have let it postpone the shutdown. Courts read this exception narrowly.⁷
Unforeseeable business circumstances. This covers closings and mass layoffs caused by events the employer could not reasonably have predicted when the 60-day clock would have started. A major client’s sudden contract cancellation or a strike at a primary supplier are the classic examples. The event must be sudden, dramatic, and outside the employer’s control.⁸
Natural disaster. Closings and layoffs caused directly by floods, earthquakes, droughts, or major storms qualify for reduced notice.

Penalties for Failing to Give Notice

A federal WARN violation creates two separate liabilities. The employer owes each affected employee back pay and benefits for every day of the violation period, capped at 60 days. Courts are split on whether that cap counts work days or calendar days, and the choice can change the total meaningfully. The employer also faces a civil penalty of up to $500 per day of violation for failing to notify the local government.³

The civil penalty can be avoided if the employer pays affected employees everything they are owed within three weeks after the closing. Voluntary severance can also offset WARN damages, but only when the payments are not already required by a contract, company policy, or other law. Severance already owed under a collective bargaining agreement, for example, cannot be credited against WARN liability.³

“Pay in lieu of notice” is not formally authorized by the statute as a substitute for 60 days’ written notice. In practice, truly voluntary pay often resolves the employer’s exposure, but employers who assume an existing severance package already satisfies WARN often find it doesn’t.

Benefits Available to Displaced Workers

Where federal WARN is a notice law, the Massachusetts provisions are mainly a benefits law. Section 71A creates a Reemployment Assistance Program with an “eligibility period” running for the first compensable week plus the next 12 consecutive weeks, giving eligible workers up to 13 weeks of supplemental benefits following the notification or certification date, whichever comes first. These payments supplement standard unemployment compensation rather than replacing it.² The money comes from a dedicated Reemployment Assistance Fund under Section 71E, separate from the general Unemployment Compensation Fund, and the program is subject to legislative appropriation.⁹

To qualify, workers must have received wages from the employer (or a predecessor) for the past four quarterly periods and must otherwise be eligible for unemployment benefits.² MassHire rapid response teams coordinate job placement, resume workshops, interview coaching, and referrals to vocational training, often visiting the worksite before the closing date.

Section 71G provides a separate health insurance benefit, with narrower eligibility than many workers expect. It covers employees who had an individually purchased health insurance plan at the time of termination and who cannot get coverage through a family member’s plan. Workers on an employer-sponsored group plan are not eligible under Section 71G, though they may have separate rights under COBRA to continue group coverage at their own expense. For those who qualify, the fund covers the monthly premium for up to three calendar months, starting from the first compensable week and ending when the three months run out or the worker finds new employment, whichever comes first.¹⁰ Payments come from the Health Insurance Benefits Fund under Section 71E, not from the employer.⁹

Workers facing a closing should contact the MassHire Department of Career Services early. Because state benefits depend on appropriation and, in some cases, commissioner certification, starting the process early is the best protection against gaps in income or coverage.⁶
