How much notice does the WARN Act require before a plant closing under 20 CFR 639?

The WARN Act requires at least 60 days' notice before a plant closing.

"WARN requires employers who are planning a plant closing or a mass layoff to give affected employees at least 60 days' notice of such an employment action." (20 CFR 639.2)

In practice, this means that employers must provide written notice to affected employees, their representatives, and local government officials at least 60 days before a planned plant closing or mass layoff, unless one of the exceptions applies, such as unforeseeable business circumstances or a natural disaster.

• Review the WARN regulations to determine if an exception applies.
• Conduct a WARN trigger analysis to identify affected employees and determine the notice requirements.
• Prepare and deliver written notice to affected employees, their representatives, and local government officials at least 60 days before the planned plant closing or mass layoff.
