Which act is relevant to the regulation of layoffs in employment law?

The WARN Act, or the Worker Adjustment and Retraining Notification Act, is specifically designed to protect workers, their families, and communities by requiring employers to provide advance notice of significant layoffs and plant closings. This act applies to employers with 100 or more full-time employees and mandates that they must give at least 60 days' notice before a layoff that affects 50 or more employees within a 30-day period. The purpose of this regulation is to allow workers adequate time to prepare for the potential loss of employment, seek other job opportunities, or upgrade their skills to enhance their employability.

The other acts mentioned focus on different aspects of employment law. For instance, the Fair Labor Standards Act governs wage and hour regulations, the Family and Medical Leave Act provides for job protection during family or medical leave, and the Occupational Safety and Health Act addresses workplace safety and health standards. None of these acts specifically address the requirements related to layoffs as the WARN Act does.
