Questions about the data & methods

About this WARN notice

What is a WARN notice?

A WARN notice is a mass-layoff or plant-closure notice an employer files with a state agency under the Worker Adjustment and Retraining Notification Act. It tells workers and the state about a large layoff or closure in advance.

Why do some notices show a future effective date?

Employers file projected layoff dates, sometimes years ahead, and the archive records them as filed. A future date is a filed plan, not a completed layoff; on this page it carries a projected marker.

What does a WARN notice tell you about an H-1B employer?

A WARN notice records a planned layoff; WARN data carries no nationality, so the notice does not say who was laid off. When the same employer filed H-1B labor applications in a window around the notice, XH1B records the pair as a displacement event and scores the match. Timing overlap is a review signal, not evidence that a noticed worker was replaced.

Is every layoff covered by WARN?

No. WARN only covers employers of a certain size and layoffs above a threshold, and the rules vary by state. A missing WARN notice does not mean no layoff happened.

Does a late or missing notice mean an employer broke the law?

Not on this site. Federal WARN requires 60 days' advance notice; statutory exceptions can shorten or excuse notice. This site publishes notices as filed and does not judge compliance.

  1. [1] XH1B method or registry · XH1B. WARN Notices (mass layoffs): source registry. Source registry entry: warnXH1B dataset description: One row per source_notice_id. The definition of a mass layoff and the layoff threshold vary by state. The threshold is typically 50 or more employees.
  2. [2] Dataset documentation · DOL OFLC. LCA public disclosure record layout (FY2026 Q3). Pages 1–4: application, DOL outcome and dates, requested positions, employer, representatives, worksites and pay unitsThis layout covers determinations issued October 1, 2025 through June 30, 2026. It documents employer-provided application fields and DOL decisions, not USCIS decisions, payroll verification, legal bills or worker-linked moves. Older layouts can differ.Checked 2026-10-17.
  3. [3] XH1B method or registry · XH1B. Displacement Model and Assumptions. Eligibility, requested-position weighting, scopes, WARN matching, and counting limitsModel outputs are estimates. A matched layoff notice does not prove that an H-1B worker replaced a laid-off worker.
