A WARN (Worker Adjustment and Retraining Notification) notice is a notice required by the federal WARN Act in the United States, which mandates that employers with 100 or more employees provide at least 60 days advance written notice of a plant closing or mass layoff affecting 50 or more employees. The notice is intended to provide affected employees with sufficient time to prepare for the loss of their jobs and to seek alternative employment. This is also why some of the layoff dates in our tracker are in the future. For more details, https://www.warntracker.com/blog/warn-act-guide

Some states have their own "mini-WARN" laws that provide additional protections or cover smaller employers not covered by the federal law. For example, California has a state law known as the California WARN Act, which covers employers with 75 or more employees and provides some additional protections, such as requiring notice to be given to employees who are terminated as well as the state. In New York, the state's Mini-WARN Act requires employers with 50 or more employees to provide 90 days' notice of a plant closing or mass layoff. So, the specifics of the WARN notice requirements can vary

Steven Zhang heard about the WARN Act from a friend, and decided to share some data analysis of the Jan 2023 Google layoffs on Linkedin. The post went viral with over 600,000 Linkedin views. The next weekend, he and Chris Talley decided to build this site to help people understand the broader layoff environment.
