The Worker Adjustment and Retraining Notification Act: Revising the Act and Educational Materials Could Clarify Employer Responsibilities and Employee Rights.
A number of factors determine whether employers are required to provide notice under the Worker Adjustment and Retraining Notification (WARN) Act. First, employers must decide if the mass layoff or plant closure at a single site will affect at least 50 employees, excluding part-time workers. For a mass layoff, employers must also consider if the layoff will affect at least 33 percent of the workforce at the layoff location (excluding part-time workers) and will be expected to exceed 6 months. Employers must then determine if at least 50 full-time workers will be laid off during any 30-day period, or for two or more groups, over a 90-day period.
If the mass layoff or plant closure has met all these criteria, it would be subject to the WARN Act's requirements, and notice must be provided at least 60 days before the first layoff. Certain layoffs and closures are exempt from advance notice, including those that involve the completion of a particular project, certain transfers or reassignments, and strikes or lockouts.
