What percentage of layoffs are covered in WARN data?

• Q: What is WARN?
• A: 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.

• Q: How does WARN work in different states?
• A: 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 from state to state, but the general principle is that it is meant to provide affected employees with advanced warning of potential job losses.

In other words, for every layoff, what % of workers meet the WARN criteria above?
