Worker Adjustment & Retraining Notification

What is a WARN?

The Worker Readjustment and Retraining Notification Act (WARN) is a law that requires employers to provide employees experiencing employment loss with a 60-day notice prior to a layoff, although some exceptions apply. The WARN protects workers, their families, and communities from the impact of mass layoffs.  

Do I need to file a WARN?

You may need to file a WARN if you experience an event that triggers a WARN. Events that trigger a WARN might include mass layoffs, plant closings,  or the sale of a business although some exceptions apply.  

How do I file a WARN?

A WARN notice must be provided to either affected workers or their representatives (e.g. a labor union); to the State Dislocated Worker Unit; and to the appropriate unit of local government. No particular form of notice or record is required but the content of the WARN notification must be specific and in writing.  Failure to provide adequate notice to employees may result in prosecution and penalties.

Who do I contact?

To file a WARN or for more information, please email or call 303-318-8267.
