New Jersey recently became the 16th state to enact its own plant closure and mass-layoff notification law that supplements the Federal Worker Adjustment and Retaining Notification Act of 1988 (the “Federal WARN Act”). Like the Federal WARN Act, New Jersey’s act, entitled the Millville Dallas Airmotive Plant Job Loss Notification Act (the “New Jersey WARN Act”), applies generally to employers with 100 or more full-time employees, but it differs from the Federal WARN Act in several important respects, including providing for broader coverage and notification requirements and more stringent penalties for compliance failures. The New Jersey WARN Act provides the same mandatory notice period of 60 days prior to a mass layoff or plant closing. However, the New Jersey WARN Act provides additional protections to employees, as described in this article.
