The data above is free forever — CC BY 4.0, no login, no API key, no delay, rebuilt daily.

If you only care about particular employers or states, you do not have to re-download the whole file and diff it yourself. WARN Watch runs your list against every daily refresh and gives you a private alert page, an RSS feed and an optional Slack/Discord/Teams webhook — no login.

How much notice did California workers actually get?

Of the 10,285 California notices in the full archive that carry both a notice date and an effective date, 6,251 (60.8%) span fewer than 60 days.

Year	Notices with both dates	Under 60 days	Share
2026	951	453	47.6%
2025	1,295	582	44.9%
2024	1,475	885	60.0%
2023	1,128	929	82.4%
2022	706	479	67.8%
2021	522	358	68.6%
2020	860	707	82.2%
2019	670	400	59.7%
2018	605	315	52.1%
2017	574	277	48.3%
2016	564	265	47.0%
2015	658	382	58.1%
2014	277	219	79.1%

Read this before quoting the notice-period numbers. Several states publish the date the state received the filing rather than the date workers were notified, so an interval a little under 60 days is frequently state processing lag rather than a short notice. That is why this dataset publishes state-level and year-level shares and never ranks named employers by notice length.

Method and exclusions: notice-period analysis.

Use it, or keep watching it

This dataset is one cut of a single daily rebuild: 61,309 US WARN Act layoff notices from 48 state agencies, 1988 to today, one schema, no login, no delay, CC BY 4.0. Snapshot as of 2026-09-13; the files above are rebuilt every day, so the live count is the truth.

Look something up right now — free, no signup, nothing to install. Check any employer or state against the last 180 days → It runs in your browser against these same files.

Building something with it? The same files are a free HTTP API — JSON and CSV, no key, no signup, access-control-allow-origin: * so fetch() works from a browser: endpoints, schema and curl examples →

Or have it watch a list for you. Coming back to look is the part a CSV cannot do. WARN Watch — $49 for a year, one payment, nothing auto-renews, 14-day refund, no login: up to 500 employer names plus whole states, matched on every daily refresh, delivered to a private alert page + calendar (.ics) + RSS + an optional Slack / Discord / Teams webhook. Every alert carries that employer's whole filing history from the archive, which a keyword rule on an RSS feed cannot see. There is no built-in email — we do not claim one.

Reaching a human. WARN Feed is published by APProjects, an automated data publisher — that is stated plainly rather than dressed up. Corrections, coverage gaps, schema questions and refund requests all go here and are read: open an issue. Payments are handled by Gumroad as merchant of record, so an invoice can carry your company name.
