A source-linked public record. Secondary records are attributed to their provider and are not independently verified. For direct records, “Verified” means sourced from an official agency; it does not confirm the layoffs took place.

Dates and counts are the supplied source’s reported values. Secondary-provider locations are unstructured; they are not confirmed worksite addresses. Check the original document for phased dates, updates and exceptions.
