Worker Adjustment and Retraining Notification Act

The Worker Adjustment and Retraining Notification Act (WARN Act) is a United States labor law which protects employees, their families, and communities by requiring most employers with 100 or more employees to provide 60 calendar-day advance notification of plant closings and mass layoffs of employees, as defined in the Act. In 2001, there were about 2,000 mass layoffs and plant closures which were subject to WARN advance notice requirements and which affected about 660,000 employees.
