How to read WARN notices
- What is a WARN notice?
- A WARN notice is an employer’s advance written announcement, filed with a state workforce agency, of a planned mass layoff or plant closing. The federal WARN Act generally requires 60 or more days of notice from larger employers, and several states add their own notice rules. The notice itself is a public record published by the state. The WARN Act, in the glossary.
- Is a WARN notice the same as a completed layoff?
- No. A WARN notice is an employer’s advance ANNOUNCEMENT of a planned mass layoff or closure, generally required 60 or more days ahead. Plans are sometimes rescinded, reduced, or rescheduled, and the headcount is the employer’s estimate at filing time.
- Does no WARN notice mean no layoffs?
- No. WARN generally covers larger employers (typically 100 or more employees) above event-size thresholds, state rules differ, and this site currently tracks a subset of state disclosure sources. Smaller or untracked reductions do not appear here. Which states are tracked.
- Do these notices show H-1B workers replacing laid-off workers?
- No, and the reverse cannot be concluded either. LCA filings and WARN notices are separate public records that may involve different divisions, worksites, job types, and time periods. This site presents both records side by side and draws no causal conclusion.
- Does an H-1B filing mean a visa was granted?
- No. A Labor Condition Application is the wage-and-worksite filing an employer makes before petitioning. Many certified LCAs never become petitions, and an LCA is not a visa. What an LCA is.
- How do I report an error in the layoffs data?
- Email hello@h1b.report with the employer name, the state, the notice date, and what looks wrong. Reports are reviewed by hand, verified corrections are applied with the next data refresh, and the matching rules are documented on the methodology page. How WARN data is matched and published.
