# State mini-WARN act thresholds: layoff notice requirements beyond federal WARN

**Canonical, always-current version: https://referencesource.org/state-mini-warn-act-thresholds/**

  it re-verifies on a cadence this snapshot does not)

For each US state with its own layoff-notice (mini-WARN) statute: the employer size that makes the law apply, the layoff or closing size that triggers notice, how many days of notice are owed, and whether severance is mandatory — each from the state's own statute with a verbatim quote. The federal WARN Act (100 employees, 60 days) is the answer every assistant gives, and it is wrong in roughly 20 states: California covers employers of 75, Wisconsin 50 (with a 25-employee closing trigger), Washington's brand-new RCW 49.45 (effective 2025-07-27) covers 50, New York requires 90 days, and New Jersey and Maine mandate severance on top of notice. Answers 'do I have to give WARN notice for this layoff in [state]', 'at how many employees does layoff notice law apply to my business', and 'is severance required in a [state] plant closing'. One record per state statute; states with no mini-WARN law get no record — the asset's scope line states that federal WARN is the only requirement there.

## Provenance — what every record carries

Every record carries `source` (the URL the value was read from) and
`source_quote` (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its `url`.

Facts are not copyrightable; what this dataset takes from each source is a
fact plus a short attributed quote linking back to the page that states it.
