The U.S. Department of Labor explains that federal WARN coverage depends on the employer, worksite, event size, workforce share, timing, and exceptions. PlainLayoffs compiles 9,006 public filings, covering 1,433,550 affected workers as of September 2026, directly from the issuing state workforce agencies, and renders them into employer, industry, and state pages from a structured database. Our sourcing standards, update cadence, and corrections process are documented in our editorial & corrections policy, about, and methodology pages.
