This page shows every WARN Act notice we have on record for Colorado through Jan 8, 2021 - 32,116 workers across 266 filings - but our feed has not updated since then (see the note above). The federal Worker Adjustment and Retraining Notification Act of 1988 requires employers with 100 or more staff to give 60 days' written notice before a mass layoff (500+ workers at a site, or 50+ when that is at least a third of the workforce) or a plant closing; Colorado reports through its own rapid-response and dislocated-worker program. Each notice below lists the employer, the number of jobs affected, the location, and the filing date, drawn directly from the state's published filings, use them to see which employers and industries are cutting, and when.
Colorado WARN threshold: Employers must file WARN notices when laying off 100+ workers. This matches the federal WARN Act threshold.

Reading Colorado's WARN Act Filings
Colorado has 266 WARN notices on record affecting 32,116 workers, with the most recent filing dated Jan 8, 2021. Reporting floor: 100+ workers (aligned with federal minimum).
Average notice size: 121 workers - smaller events (single-line closures, partial-facility layoffs at the WARN threshold). WARN Act framework + worker rights →
A few caveats are worth keeping in mind when you read these numbers. WARN notices are advance warnings, not confirmed outcomes, some filings are later withdrawn, postponed, or end up affecting fewer people than first projected, while voluntary buyouts and slow attrition never appear in this dataset at all. The law also exempts smaller employers and any layoff below the reporting threshold, so a quiet state on this page is not automatically a healthy labor market; it may simply file fewer covered notices. Treat these totals as a floor on visible disruption and a timeline of the largest, best-documented cuts, then open an individual notice to see the employer, the location, and the effective date behind each figure.
