Coverage limits and how to read sector WARN totals
WARN notices cover qualifying events, not every workforce reduction: federal coverage depends on the employer, worksite, event size, workforce share, timing, and exceptions, while state rules can differ. At an average of 326 workers per notice, filing size in Mining & Oil and Gas Extraction tracks with multi-department reductions and site-level shutdowns. Read the record alongside BLS employment data; WARN flags the reported event, not its cause or an individual worker's entitlement.
