Methodology
Our guides draw on WARN Act notices filed with state labor agencies under the federal Worker Adjustment and Retraining Notification Act, which requires 60 days' notice before a mass layoff affecting 50 or more workers, plus U.S. Department of Labor reporting. Every figure is sourced. Counts, dates, and worker totals come directly from those filings, referenced inline so each claim traces back to the originating notice.
The aim is plain language. We translate dense regulatory filings into explanations a general reader can act on, and when state agencies report differently or revise a notice, we flag the variation where it appears. Our editorial process includes regular reviews to keep figures accurate and current.
