New Jersey WARN Act: Notice, Severance, and Penalties

The New Jersey WARN Act requires private employers with 100 or more employees to give 90 days’ written notice before a mass layoff, plant closing, or transfer of operations, and to pay every affected worker severance equal to one week of pay for each full year of service.¹ Formally titled the Millville Dallas Airmotive Plant Job Loss Notification Act (N.J.S.A. 34:21-1 et seq.), the statute goes considerably further than the federal WARN Act, and 2023 amendments made it stricter still. Miss the notice window and each employee is owed an additional four weeks of pay on top of the standard severance.

Which Employers Are Covered

Any private employer with 100 or more employees is covered, counting full-time and part-time workers together.² Government agencies are excluded. Nonprofits that hit the headcount are in.³

A common misreading: the statute does not say “100 or more employees in New Jersey.” It says “100 or more employees,” full stop. A national company with 100 workers across the country and only 30 in New Jersey is still covered for those 30 workers. What is limited to New Jersey is the “establishment,” defined as a single location or group of locations that includes facilities in the state.³

One additional filter: the establishment must have been in operation more than three years.³ A New Jersey office that opens and closes within 18 months does not trigger NJ WARN, no matter how many employees lose their jobs. Temporary construction sites are excluded from the definition entirely.

What Triggers the Notice and Severance Obligation

Three kinds of workforce reductions bring the statute into play:

A termination of operations, meaning a permanent or temporary shutdown of a facility or a distinct part of one, resulting in 50 or more job losses in any 30-day period.
A transfer of operations to a different location, causing 50 or more terminations in any 30-day period.
A mass layoff of 50 or more employees at or reporting to New Jersey facilities during any 30-day period.³

Since the 2023 amendments, “establishment” pulls in all of an employer’s New Jersey facilities together. Twenty layoffs in Newark and 35 in Camden within a 30-day window add up to 55 for the threshold analysis.⁴

The 90-Day Aggregation Rule

Spacing layoffs out to stay under 50 does not work. If two or more rounds of terminations happen at the same establishment within a 90-day window and together exceed the 50-employee threshold, they are treated as one triggering event.² The only way to keep separate rounds separate is to show that each had a distinct cause. Quiet, rolling reductions can cross this line without anyone noticing, which is why running headcount tallies on a 90-day basis matters.

The 90-Day Written Notice

Covered employers must deliver written notice at least 90 days before the first termination in a covered event.¹ If the federal WARN Act ever required a longer period, the longer one controls, but since federal WARN sits at 60 days, the New Jersey 90-day period governs in practice.

Notice has to reach four recipients:

Each affected employee whose position is being eliminated.
The Commissioner of Labor and Workforce Development.
The chief elected official of the municipality where the establishment is located.
Any collective bargaining unit representing employees at the establishment.¹

Notices to individual employees, local officials, and unions have to be delivered in hard copy. The Commissioner’s notice is filed through the New Jersey Department of Labor’s online portal.⁵ The 90-day clock runs from receipt, not from the postmark, so employers building the timeline should leave room for delivery and keep proof of it.

Mandatory Severance Pay

Every employee terminated in a covered event is entitled to severance equal to one week of pay for each full year of service.¹ The pay rate is the higher of two figures: the employee’s final regular rate of compensation, or the average regular rate over the last three years of employment. A 12-year employee earning $1,500 a week is owed at least $18,000.

If a collective bargaining agreement or existing company severance plan pays more, the employer pays the greater amount.² The statute also treats this severance as compensation earned in full upon termination rather than a benefit that vests over time, which aligns it with “wages” under New Jersey’s Wage Payment Law.

Waivers and Releases

Employers cannot condition statutory severance on signing a release. A waiver of the right to NJ WARN severance is not effective without approval from the Commissioner of Labor or a court.² An employer can offer extra severance above the statutory floor and tie that extra amount to a release, but the baseline payment goes out either way.

Penalty for Short Notice

If the employer provides fewer than 90 days of notice, every affected employee gets an additional four weeks of pay on top of the standard severance.¹ The penalty is the same whether notice was 89 days short or 89 days late: skipping notice for 200 workers means 800 additional weeks of pay before any litigation costs. Partial compliance is a losing strategy. Either hit the full 90 days, or budget for the surcharge.

How NJ WARN Differs From Federal WARN

Complying with the federal WARN Act does not satisfy the New Jersey statute. Both apply at the same time, and NJ WARN is stricter on nearly every point.

Notice period: federal WARN requires 60 days; New Jersey requires 90.⁶
Severance: federal WARN requires none. New Jersey mandates one week per year of service, plus four extra weeks per employee if notice falls short.
Employee counting: federal WARN excludes workers who averaged fewer than 20 hours per week or worked less than six months in the past year. NJ WARN counts all employees regardless of hours or tenure.⁶
Site versus statewide counting: federal WARN measures layoffs at a single site of employment. NJ WARN aggregates across all of an employer’s New Jersey locations.

One coordination rule helps avoid double payment: any federal WARN back pay owed for violating the 60-day federal requirement is credited against the NJ WARN severance for the same event.¹

Exceptions Are Narrow

Federal WARN recognizes three well-established exceptions that shorten the 60-day federal notice: the faltering company exception, unforeseeable business circumstances, and natural disaster.⁷ These do not automatically reduce the New Jersey 90-day requirement. Legislation has been introduced to add specific NJ WARN carve-outs for natural disasters, fires, national emergencies, acts of war, civil disorder, industrial sabotage, and closures triggered by loss of Medicare or Medicaid certification or license revocation, but the availability and scope of these exceptions is still developing. Employers hit by a sudden, catastrophic event should consult counsel before assuming any federal shortcut applies.

Enforcement and Employee Remedies

The Department of Labor does not directly enforce NJ WARN. Employees pursue claims in court, and a successful claim can recover unpaid severance, lost wages, benefits, and attorney’s fees.

The real exposure for employers comes from the interaction with the Wage Payment Law. Because NJ WARN classifies severance as compensation earned in full upon termination, unpaid or late severance can qualify as unpaid wages, which under that statute carries liquidated damages of up to 200 percent on top of the underlying amount. An employer that stiffs 100 workers on severance can end up owing roughly triple the original obligation.

Effect on Unemployment Benefits

Collecting NJ WARN severance does not delay or reduce your New Jersey unemployment insurance. The state does not count severance pay as wages when calculating benefit amounts.⁸ You can file as soon as you are separated, even while a severance payment is still being processed.

If the Employer Files for Bankruptcy

The severance obligation does not disappear in bankruptcy, but where it sits in the creditor line determines whether workers actually collect. Layoffs that happen before the bankruptcy petition produce priority unsecured claims up to a per-employee cap, with anything above the cap dropping to general unsecured status. Layoffs that happen after the filing may produce administrative-expense claims, which are paid ahead of most other creditors. Federal WARN back pay for the same event is credited against the New Jersey severance so workers do not recover twice. The classification is technical, and affected employees generally need to file a proof of claim with the bankruptcy court to protect their position.
