Severance Pay Laws in New Jersey
New Jersey sits in a tiny club of US states that legally mandate severance pay for certain layoffs. The Millville Dallas Airmotive Plant Job Loss Notification Act — commonly called the NJ WARN Act — was amended in 2019 and the toughest provisions took effect in 2023. As amended, the law now requires employers with 100 or more full-time employees to pay severance of one week of pay per year of service whenever they conduct a mass layoff of 50 or more workers at a single establishment. The severance is not optional and it does not depend on whether the employer chose to give notice.
On top of the statutory severance, NJ WARN also requires 90 days of advance written notice for any mass layoff, plant closing, or transfer of operations that meets the threshold. That is 30 days longer than the federal WARN Act's 60-day minimum. If the employer skips the 90-day notice, it owes an additional four weeks of pay per affected employee on top of the year-of-service severance. In practice, a long-tenured worker can walk away with substantially more than the offer first put in front of them, simply by enforcing what the statute already provides.
For employees who fall outside the WARN threshold — smaller employers, or layoffs of fewer than 50 workers — New Jersey severance reverts to a negotiated, contractual matter. There is no general state mandate for individual terminations. The leverage in these cases comes from what the employer wants in return: a signed release of claims. The broader the release, the more the release is worth, and the more room there is to negotiate the dollar figure up. New Jersey courts have also been receptive to wrongful-termination, retaliation, and Conscientious Employee Protection Act (CEPA) claims, which often surface during severance negotiations.
Final wages in New Jersey are due by the next regular payday following the separation. Unused vacation is treated as wages if the employer's policy or contract makes it accruable and payable on termination. New Jersey also enforces non-compete clauses more readily than California or some peer states, but courts will scrutinize the geographic scope, duration, and the employer's legitimate business interest. If a separation agreement asks you to waive future claims under CEPA, the Law Against Discrimination, or the New Jersey Wage Payment Law, that waiver is enforceable only if the agreement satisfies state law requirements, including a knowing-and-voluntary standard for older workers under the ADEA.
If you are over 40 and signing a separation agreement, the federal Age Discrimination in Employment Act gives you 21 days to review and 7 days to revoke after signing. For group layoffs, the review window stretches to 45 days. New Jersey employers covered by NJ WARN must also issue the statutory severance regardless of whether you sign the release — the severance and the release are technically separate transactions, even if they show up in the same document.
How Much Severance Are New Jersey Workers Owed?
A New Jersey worker covered by NJ WARN can reasonably expect at least one week of severance per year of service, no signature required. On top of that, if 90 days of notice was not provided, the employer owes the equivalent of four additional weeks of pay. Beyond the statutory floor, larger employers in pharmaceuticals, finance, and biotech routinely negotiate up to two to four weeks per year of service for senior individual contributors and significantly more for managers and directors.
The dollar amount LayoffMath surfaces is the gap between what employers in your specific role-and-tenure profile typically pay and what you were offered. For New Jersey workers, that gap tends to widen when WARN-trigger thresholds are crossed and narrows for employees at small employers who have weaker statutory protection.

Frequently Asked Questions — New Jersey Severance
Does New Jersey require employers to pay severance?+
Yes, in specific circumstances. Under the amended NJ WARN Act, employers with 100 or more full-time employees must pay severance of one week per year of service whenever they conduct a mass layoff of 50 or more workers at a single establishment. The payment is mandatory and independent of any separation agreement. Outside that threshold — smaller employers, individual terminations — there is no general state severance mandate, and severance is contractual.
How does the NJ WARN Act differ from the federal WARN Act?+
Three big differences. First, NJ WARN requires 90 days of advance notice (federal WARN requires 60). Second, NJ WARN includes a one-week-per-year statutory severance mandate; federal WARN has no severance requirement. Third, the penalty for skipping the 90-day notice is an additional four weeks of pay per affected employee on top of the statutory severance. NJ WARN applies to employers with 100+ employees and mass layoffs of 50+ at a single establishment.
Can my New Jersey employer make me sign a release to receive the NJ WARN severance?+
No. The statutory severance under NJ WARN is owed regardless of whether you sign a release of claims. Many employers bundle the statutory severance and a release agreement in a single document, which can be confusing — but the law makes the severance independent. If you are also being offered additional severance above the statutory minimum, the additional amount can be tied to a release. Read the agreement carefully and consider consulting an employment attorney, especially if you are over 40 (where ADEA review and revocation rights apply).
