What is a WARN notice?
A WARN notice is an advance notification an employer must provide under the Worker Adjustment and Retraining Notification (WARN) Act — generally 60 days before a covered plant closing or mass layoff — naming the affected site and the number of workers.
The federal WARN Act generally applies to employers with 100 or more employees and requires 60 calendar days' advance written notice of a covered plant closing or mass layoff, to affected workers (or their representatives) and to state and local officials. Many states have their own 'mini-WARN' laws with broader thresholds.
Notices are collected by state dislocated-worker units and are public. A WARN notice names the employer, the worksite, the number of workers affected, and the layoff/closing date.
That legally mandated advance window is used by staffing and outplacement firms (to pre-recruit displaced talent), by lenders and insurers (as a distress signal), and by special-situations investors.
