What is WARN Act?

Worker Adjustment and Retraining Notification Act

Quick Answer

The WARN Act, or Worker Adjustment and Retraining Notification Act, requires employers to provide advance notice of significant layoffs or plant closings. This law aims to give workers time to prepare for job loss and seek new employment.

Overview

The WARN Act is a federal law that mandates employers with 100 or more employees to give at least 60 days' notice before mass layoffs or plant closures. This notice must be provided to affected workers, their representatives, and local government officials. The goal is to help employees prepare for the transition, whether by finding new jobs or accessing retraining programs. When a company plans to lay off a large number of employees, the WARN Act ensures that those workers are not caught off guard. For instance, if a factory plans to close and lay off 150 workers, they must inform everyone involved two months in advance. This notice allows employees to seek new job opportunities or enroll in training programs to improve their skills, making it easier for them to find new employment. The importance of the WARN Act lies in its protection of workers' rights during times of economic change. By requiring advance notice, the law helps lessen the shock of sudden unemployment and provides a framework for support. In the context of Employment Law, the WARN Act serves as a crucial safeguard for workers, ensuring they have the time and resources needed to adapt to significant job changes.
