How many days of notice does New Jersey require?

90 days is the longest notice period the state's law sets for the employer's notice. The federal Act requires 60 days, and the federal rule applies in every state.

New Jersey WARN Act: who is covered and how much notice

New Jersey has its own layoff notice law on top of the federal WARN Act. This is what it says, read from the state’s own pages as of 2026-10-27, with the sources.

The rule

Since the April 10, 2023 amendment, employers with 100 or more employees must give 90 days’ notice, and a mass layoff is 50 or more workers at a worksite. An employer that gives less notice owes each affected employee one week of pay for each full year of service, and four more weeks if notice is short.

How it differs from the federal rule

Longer notice (90 days) and mandatory severance pay, neither of which the federal Act has.

Check: Some New Jersey Department of Labor pages still describe the earlier 60-day rule. This summary follows the amended statute text. Amendments after those pages were published were not checked.

This is general information, not legal advice. The federal WARN Act applies in every state as well; see the WARN Act in plain language.
