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

The NJ WARN Act requires New Jersey employers with 100 or more workers to give at least 90 days’ written notice before a plant closing, transfer of operations, or mass layoff that costs 50 or more employees their jobs, and to pay one week of severance for every full year each affected worker has been on the payroll.¹ Falling short on notice adds another four weeks of pay per employee on top of that severance. The law’s formal name is the Millville Dallas Airmotive Plant Job Loss Notification Act, N.J.S.A. 34:21-1 et seq., and it is considerably stricter than the federal WARN Act.

Which Employers Are Covered

Any business that employs 100 or more people in New Jersey is covered, counting full-time and part-time workers alike.² The headcount takes in every worker who reports to or is assigned to a New Jersey facility. That is broader than the federal WARN Act, which leaves part-timers out of its 100-employee threshold, so some employers who sit under the federal cutoff still owe notice in New Jersey.³

What Triggers the Law

Three kinds of business decisions activate the notice and severance requirements, and each is measured against the same threshold: 50 or more employees losing their jobs within a 30-day window at a single establishment.⁴

Termination of operations — a permanent or temporary shutdown of an entire establishment, or of one or more facilities within an establishment, causing 50 or more terminations.²
Transfer of operations — moving a facility or operating unit, inside or outside the state, that eliminates 50 or more jobs at the original site.⁵
Mass layoff — a reduction in force, unconnected to a closing or transfer, that eliminates 50 or more positions at or reporting to one establishment within 30 days.²

The 50-employee number is a flat trigger. The federal WARN Act instead requires 50 employees who also represent at least 33 percent of the workforce, or alternatively 500 employees.³ New Jersey drops the percentage test, so state law catches layoffs the federal law would ignore.

Which Departures Count Toward 50

The statute defines a termination as a layoff without a commitment to reinstate the employee within six months. Several departures do not count:⁵

Voluntary quits and retirements.
Discharges for misconduct related to job performance or conduct.
Layoffs of seasonal employees at the natural end of a season.
Workers offered the same position, or one with equivalent pay, benefits, and status, at a New Jersey location no more than 50 miles from the original workplace.

A layoff first announced as six months or less that later runs longer can still avoid WARN treatment if the extension results from unforeseeable business circumstances and the employer gives notice as soon as the longer timeline becomes apparent.⁵

The 90-Day Notice

Written notice must reach every required recipient at least 90 days before the first termination. The statute sets the floor at “not less than 90 days, or the period of time required pursuant to the federal Worker Adjustment and Retraining Notification Act, whichever is longer,” so any future increase in the federal period would raise the New Jersey minimum automatically.⁴ Federal law currently sits at 60 days, so 90 days is the operative deadline.

Notice must go simultaneously to four recipients:⁴

Each affected employee individually.
Any collective bargaining representative for affected workers.
The chief elected official of the municipality where the establishment is located, usually the mayor.
The Commissioner of Labor and Workforce Development, filed through the Department of Labor’s online portal.⁶

The state uses the Commissioner’s filing to mobilize its Rapid Response team, which provides job placement referrals, retraining information, and benefits counseling to displaced workers.⁶ The statute does not specify a delivery method for individual employee notice, but certified mail or hand delivery with signed acknowledgment creates proof of the receipt date, which is what the 90-day count turns on. Bulletin board postings and paycheck inserts do not satisfy the requirement.

What the Notice Must Say

While the NJ WARN Act does not prescribe a template, the notice needs to give workers enough information to know what is happening and what they are owed. In practice that means:

The number of employees being terminated and each expected separation date.
The date of the closing, transfer, or mass layoff.
The reasons for the workforce reduction.
Whether positions are available at other company locations, with pay, benefits, and terms.
A disclosure of the severance the NJ WARN Act requires.
A statement of employee rights concerning wages, benefits, and pension.
A statement about the right to services from the NJ Rapid Response team.

Because most NJ WARN events also trigger the federal WARN Act, the notice should include contact information for a company representative and a statement about whether bumping rights exist. A single combined notice is simpler than issuing two separate documents.

The Mandatory Severance Payment

Every terminated employee is entitled to one week of pay for each full year of service.⁴ This obligation sets New Jersey apart from most states and from the federal WARN Act, which imposes no severance duty at all.

The weekly rate is the higher of the employee’s average regular rate of compensation over the last three years or the employee’s final regular rate.⁴ The three-year average protects a worker whose pay was cut shortly before the layoff. “Regular rate” generally means base compensation, not overtime or bonuses. Only full years count: someone with 7 years and 11 months of service receives 7 weeks.

If the employer already provides severance under a collective bargaining agreement or company plan, the employee receives whichever amount is greater. The two do not stack. Any back pay owed under the federal WARN Act for a federal violation is credited against the New Jersey severance obligation, preventing a double recovery.⁴

The statute treats this severance as compensation earned in full at the moment of termination, so it is not contingent on signing a release or on any vesting schedule.

The Penalty for Short Notice

An employer that gives fewer than 90 days’ notice owes each affected employee an additional four weeks of pay on top of the standard severance.⁴ The penalty runs per employee. In a 200-person layoff, that is 800 extra weeks of pay.

A worker earning $1,200 per week with 10 years on the job and no advance notice would be owed 10 weeks of standard severance ($12,000) plus 4 weeks of penalty pay ($4,800), a total of $16,800. Even a single day short of the 90-day mark triggers the full penalty, so many employers build a buffer of a few days into the timeline.

Because the state law incorporates a “whichever is longer” rule, a New Jersey employer who meets the 90-day requirement also satisfies the federal 60-day period. The reverse is not true: giving only 60 days meets federal law but triggers the four-week penalty under state law.

The Narrow Exceptions

Neither a mass layoff nor a termination of operations triggers the notice obligation when caused by fire, flood, natural disaster, national emergency, act of war, civil disorder, or industrial sabotage.² Two additional exceptions apply to healthcare facilities: loss of Medicare or Medicaid certification and state license revocation under New Jersey’s health care facility licensing law.⁵

The state law does not recognize two exceptions that exist under the federal WARN Act. There is no “faltering company” defense for employers actively seeking capital, and no “unforeseen business circumstances” defense for sudden events like the loss of a major client or a collapsed financing round. An employer facing either situation in New Jersey still owes 90 days’ notice unless the facts fit one of the narrow emergency categories.

How the Law Is Enforced

The New Jersey Department of Labor has no enforcement or rulemaking authority under the WARN Act. Its role is limited to receiving notices, dispatching the Rapid Response team, and making the filing portal available.⁶ The Department cannot investigate violations, impose fines, or order payment.

Enforcement runs through private lawsuits. Affected workers can sue for unpaid severance and reasonable attorneys’ fees. Because the statute characterizes severance as compensation already earned at termination, employees have a strong legal footing, and an employment attorney can move quickly before applicable filing deadlines run.

Severance, Taxes, and Unemployment

NJ WARN severance counts as supplemental wages for federal income tax. Employers generally withhold at a flat 22 percent on supplemental wages up to $1 million in a calendar year and 37 percent on amounts above that.⁷ State and payroll taxes apply on top, so the net check will be smaller than the gross figure.

Severance does not disqualify you from unemployment benefits in New Jersey. Under state unemployment regulations, receiving severance pay, whether as a lump sum or in periodic installments, does not bar eligibility.⁸ File for unemployment right after separation rather than waiting for severance to run out.

If You Just Received a WARN Notice

Check that the notice includes the required content, especially the severance disclosure and the expected termination date. Count the days: if fewer than 90 separate the date you received the notice from the date your job ends, the four-week penalty payment is likely owed.

If the employer offers a severance agreement asking you to release legal claims, read carefully before signing. You are already entitled to the statutory severance whether you sign or not, so any release should offer something above the NJ WARN minimum to be worth trading claims for.

Use the Rapid Response team, which the state activates automatically once the employer files with the Commissioner. The team provides on-site job referrals, retraining program information, and help with unemployment insurance.⁶ If notice was short or severance was not discussed, an employment attorney can evaluate what you are owed.
