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. While the 60-day period is the minimum for advance notice, this provision
is not intended to discourage employers from voluntarily providing longer periods
of advance notice. Not all plant closings and layoffs are subject to the WARN
Act, and certain employment thresholds must be reached before the WARN Act applies.
WARN sets out specific exemptions, and provides for a reduction in the notification
period in particular circumstances. Damages and civil penalties can be assessed
against employers who violate the WARN Act.
