Source: state WARN Act disclosures, normalized in the free US WARN notices dataset (CSV/JSON, no login, no delay, notices 1988+). WARN notices are advance notifications of plant closings and mass layoffs; actual layoff counts and dates can change after filing.

Only care about certain employers or states? WARN Watch, $49/year runs your list against every refresh and gives you a private alert page + RSS (free for 30 days first, no card). The data itself — every notice back to 1988 — is free.
