About this data: WARN Act filings are public records submitted to state workforce agencies when employers plan mass layoffs of 50+ employees or plant closings affecting 100+ workers. Some filings are later rescinded or modified — this tracker reflects raw filed data and may include filings that did not result in actual layoffs. Data is updated weekly from primary state agency sources.
