Before a mass layoff or a site closure, large U.S. employers must usually give 60 days' written warning — on the public record. These are those filings, searchable by company and state. No account needed.
Where this data comes from. Notices are filed with state workforce agencies under the federal WARN Act and state equivalents, collected via Big Local News' open-source warn-scraper. Filings can be amended or rescinded after they're announced — spotted an error? Use Report an error on any notice and we'll check it against the state record. Who has to file. Federal WARN covers employers with 100+ employees, and is triggered by a site closing affecting 50+ people, or a layoff of 500+ — or 50–499 where that's at least a third of the site. It has three exceptions: a faltering company seeking capital, unforeseeable business circumstances, and natural disaster. Many states set lower thresholds of their own. So a layoff missing here isn't necessarily a layoff that didn't happen.
