We are following individual WARN records from government entities, rather than crowdsourced data. Most of these records indicate exact offices and employee counts affected at each office, rather than just a single overall number for the entire company. These records are often more exhaustive than the crowdsourced data. This means they reflect small layoffs, as well as layoffs from companies which may not be large enough to be announced in the press. The timeline for filing these notices can vary -- they may be made available before or after a pub

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

We get our WARN data from a combination of: requesting records from state government agencies directly, news sources, and double checking with various layoff trackers
