Other states with large notices
Source: the open WARN Notice Register, which consolidates the WARN listings that state workforce agencies publish. Our copy is current through October 20, 2026. WARN notices are the advance filings that employers with roughly 100 or more employees send to state agencies before a layoff or closure, typically 60 days ahead. Each entry is a filing: headcounts and dates are as the employer or state recorded them, a notice can later be revised, and a count tracks company size as well as layoffs. A notice counts in the state that lists it. A notice with a statewide or unnamed site counts here and in no metro area. A listing that repeats an earlier one is counted once, and a notice the register labels is left out of the counts. How to read layoff notice data sets out what the notices can and cannot say and why some are missing. Informational only; not legal, immigration, or financial advice.
Wage data: U.S. Department of Labor OFLC LCA Disclosure Data and U.S. Bureau of Labor Statistics OEWS. LCA filings reflect sponsored-worker wage offers, which skew toward mid-large employers and specific occupations — treat any estimate built from a small sample cautiously.
