US WARN Layoffs Dataset

A cleaned, event-level dataset of United States layoff and plant-closure notices filed under the WARN Act (Worker Adjustment and Retraining Notification), plus a small set of layoff disclosures from SEC 8-K filings. Compiled and maintained by Workopia.

WARN notices are public records that employers are legally required to file with state workforce agencies ahead of mass layoffs or plant closings. This dataset normalizes those filings across states into a single, analysis-ready table.

At a glance


Events	18,468
Total employees affected	2,306,915
Notice-date range	2004-01-12 → 2026-06-10
Geographic coverage	United States, 35 states
Primary source	State WARN portals (CA, TX, NJ, IL, WA, MD, …)
Secondary source	SEC 8-K Item 2.05 disclosures (140 events)
Granularity	One row per filed notice
PII	None — company / facility level only

Density note. Coverage is sparse before ~2015 and dense from 2020 onward (COVID-era spike, then a 2025–2026 rise). Treat pre-2015 years as a thin historical tail, not a complete record. The dataset reflects WARN's universe (large layoffs above state thresholds, plant closings) — it is not a census of all U.S. job losses.

Known limitations

—U.S.-only. Non-U.S. layoffs are not included in this release.
—Industry & ticker are sparse (naics2 ~8%, industry ~51%, ticker ~0.75%). Sector- and equity-level analysis requires additional enrichment.
—WARN is not exhaustive — thresholds, exemptions, and state-by-state filing differences mean smaller layoffs and some states are underrepresented.

Suggested uses

—Tracking U.S. layoff trends over time (national and by state)
—Labor-market nowcasting and event studies
—Training/evaluation data for entity normalization and employment NLP
