New Jersey WARN Notices: 90-Day Rule, Severance, and Penalties

The New Jersey WARN Act requires private employers with 100 or more workers to give at least 90 days’ written notice before a mass layoff, plant closing, or transfer of operations that will cost 50 or more employees their jobs. It also requires those employers to pay severance of one week’s pay for every full year you worked there, with an extra four weeks tacked on if the notice was late or missing. For workers, that is the heart of it: advance warning and a statutory payout, both enforceable in court.

Who the Law Covers

The statute applies to any private business operating in New Jersey that employs 100 or more people.¹ Government agencies and public employers are not covered, because the law defines “employer” as a private entity.²

Part-time workers count. The federal WARN Act carves out employees averaging fewer than 20 hours per week; New Jersey’s statute contains no such exclusion.³ If you are a part-timer at a large New Jersey employer and your job is cut, you are protected.

One age limit on the workplace matters: an “establishment” must have been in operation for more than three years to fall under the law.² A location that opened 18 months ago and shuts down is not covered. Temporary construction sites are also excluded by definition.

What Triggers the Notice Requirement

Three kinds of events trigger the law when they result in 50 or more terminations within any 30-day period:¹

A mass layoff that cuts 50 or more positions without a closure or move.
A termination of operations, meaning the permanent or temporary shutdown of an establishment or a unit inside it.
A transfer of operations to another location, in or outside New Jersey, permanent or temporary.

Only employees who have worked for the employer for at least six months during the previous 12 months are counted toward the 50-employee threshold.² A newer hire does not help trigger coverage, though they can still be protected once the threshold is met.

Cuts Across Multiple Locations Add Up

New Jersey counts affected workers across all of an employer’s locations in the state. The statute defines “establishment” to include “a group of locations, including any facilities located in this State.”² An employer who lets 20 people go at one office, 15 at another, and 20 at a third within 30 days has hit the 50-person trigger, even though no single office lost 50 jobs. This is the opposite of the federal rule, which measures at a single physical site.³

The 90-Day Notice

A covered employer must deliver written notice at least 90 days before the first termination takes effect.¹ That is a full month longer than the 60 days required under federal WARN, and it gives workers more runway to find a new job, enroll in retraining, or plan around a coming income drop.

The notice must go to four recipients:⁴

Each affected employee, in hard copy.
Any union representing employees at the establishment.
The chief elected official of the municipality where the establishment sits, in hard copy.
The Commissioner of Labor and Workforce Development, filed through the Department’s online portal.

A compliant notice identifies the legal name and address of the establishment, says whether the event is a mass layoff, closure, or transfer, states when the first separations will happen along with the schedule for later ones, and lists the job titles affected and the workers holding them. The Department of Labor publishes an official form that captures all of this.⁴

Your Severance Pay

New Jersey is one of very few states that forces employers to pay statutory severance when a WARN event happens. The formula is one week of pay for each full year of service.¹ Twelve years at the company means 12 weeks of pay. Four years and eight months means four weeks, because partial years do not round up.

The rate used is whichever is higher: your average regular rate of compensation over the last three years with the employer, or your final regular rate of pay.¹ A recent raise usually makes the final rate control. A recent pay cut makes the three-year average work in your favor.

The statute treats this severance as compensation earned in full on the date you are terminated, so it belongs in your final paycheck rather than being stretched out in future installments.⁵

You Cannot Quietly Sign It Away

The law is explicit about waivers. A worker’s waiver of WARN severance rights has no legal effect unless it is approved by either the Commissioner of Labor or a court.⁵ If a separation agreement in front of you includes a release of WARN severance, that release does not bind you unless it has gone through one of those two channels. This is a stronger protection than most workers realize.

If the Company Already Pays Severance

Where an employer already provides severance under a union contract or company policy, you get the greater of the two amounts rather than both.⁵ Any back pay owed under the federal WARN Act for short notice is credited against the state severance obligation.

Taxes

Severance is taxable income in the year you receive it. Your employer must withhold federal and state taxes and report the payment on your W-2.⁶ A lump sum on top of wages you already earned that year can push the pay period into a higher withholding bracket, so plan the cash flow accordingly.

If the Notice Was Short or Never Came

When an employer gives less than 90 days’ notice, the penalty is automatic: an extra four weeks of pay to each affected employee, on top of the standard severance calculation.¹ A 10-year employee who got no notice at all is owed 10 weeks of standard severance plus 4 weeks of penalty pay, for 14 weeks total.

Affected workers can sue in New Jersey Superior Court, individually or as a group. A court can award compensatory damages for lost wages and benefits plus reasonable attorney’s fees and costs, though the compensatory damages are capped at the severance the employer should have paid under the statute.⁵ When a worker or representative files on behalf of a group, the Department of Labor must be told so it can notify everyone affected.

The Only Real Exception Is a Natural Disaster

The federal WARN Act lets an employer shorten its 60-day notice when “unforeseen business circumstances,” a “faltering company,” or a natural disaster is behind the layoff.⁷ New Jersey recognizes only one of those: a natural disaster such as a flood, earthquake, or fire.⁵

Losing a major client overnight, a supply chain collapse, a sudden market downturn, even a strike or lockout: none of these excuse short notice under New Jersey law. If an employer tells you the layoff is sudden and that is why there was no notice, that explanation generally does not relieve them of the obligation to pay the 4-week penalty.

What Happens After the Notice Is Filed

Once the Department of Labor receives a WARN notice, it typically sends the state’s Rapid Response Team to the affected worksite. The team coordinates resume help, job referrals, and information about unemployment insurance eligibility at no cost to workers.⁴ For workers coming off long tenure at one employer, that structured transition support can shorten the gap between jobs.

The Department’s enforcement role is limited, though. It dispatches the Rapid Response Team and publishes the WARN notice form, but it does not investigate violations or sue on workers’ behalf. If you believe your employer skipped the notice, miscalculated your severance, or tried to force a waiver on you, enforcing those rights means filing in Superior Court.
