# Colorado WARN Act layoff notices — every filing we hold since 2015, one CSV, rebuilt daily

**838 Colorado WARN notices** — every one this dataset holds, back to **2015** — free to download in full: no paywalled years, no login, no account · most recent notice filed **2026-09-10**
· state source last checked **2026-09-18T12:26Z** · official source: [Colorado Department of Labor and Employment — WARN notices](https://cdle.colorado.gov/employers/layoff-separations/layoff-warn-list).

Colorado employers must file a WARN Act notice with the state before a qualifying
mass layoff or plant closing. This page is generated from those filings, cleaned
into one schema shared with 47 other states, and rebuilt every day. Nothing here
is behind a login.

> **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, a calendar (.ics), an RSS feed and an optional Slack/Discord/Teams webhook — no login.
>
> **[Try it free for 30 days — no card](https://approj.gumroad.com/l/warn-free-watch)** (up to 3 employers or one state) · then **$49/year**, one-off, no auto-renew, 14-day refund · [see a real alert page first](https://approjects-warn-act-notices.static.hf.space/watch-sample.html)

## Employers that have filed the most Colorado WARN notices

76 employers have filed two or more Colorado notices. The 25 most
frequent filers, rolled up on the normalized employer name (`company_canonical`),
with every notice counted from the free file above. "Workers affected" sums the
headcount on the notices that state one; it is a floor, not an estimate.

## How much notice did Colorado workers actually get?

Of the **479** Colorado notices in the full archive that carry both a notice date and an effective date, **245** (**51.1%**) span fewer than 60 days.

| Year | Notices with both dates | Under 60 days | Share |
| --- | ---: | ---: | ---: |
| 2026 | 39 | 11 | 28.2% |
| 2025 | 63 | 24 | 38.1% |
| 2024 | 67 | 20 | 29.9% |
| 2023 | 65 | 25 | 38.5% |
| 2022 | 20 | 8 | _n<30_ |
| 2021 | 35 | 17 | 48.6% |
| 2020 | 165 | 131 | 79.4% |
| 2019 | 25 | 9 | _n<30_ |

**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.

<!-- warn-feed:offer:start -->
## A layoff record you can audit, not just download

This dataset is one cut of a single daily rebuild: **61,345 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 **2026-09-19**; the files above are
rebuilt every day, so the live count is the truth.

Several projects publish a current WARN scrape and two of them carry more rows
than we do. None of them publish what the records **used to say**:

- **638 observed changes to already-published notices, logged daily since 2026-08-31.**
  `data/revisions.csv` records every field that differed between two consecutive
  daily builds — employee counts, effective dates, notice types, company names —
  with the old value, the new value and the date we saw it. We publish the
  observation and not the cause: a change is equally explained by the agency
  amending the notice or by our own parser improving, and we do not guess which
  (see `data/revisions.README.txt`). A scrape that starts tomorrow cannot backfill
  any of it; it only exists if someone was watching.
- **6,799 notices whose state agency page no longer lists them.** Agencies
  take notices down. We keep them, flagged as archive-only, so a count you ran
  last year still reconciles.
- **Point-in-time employer identity.** The ticker crosswalk resolves a filer to
  the company as it existed at the time of the notice — Kmart, Sears Holdings,
  Symantec — not to whatever is on today's ticker file.

If you have to defend a number to an editor, a referee or a compliance reviewer,
that provenance layer is the part you cannot rebuild yourself.
[How to cite this dataset →](https://github.com/APVentureEngine/warn-act-notices/blob/main/CITATION.cff)

**Look something up right now — free, no signup, nothing to install.**
[Check any employer or state against the last 180 days
→](https://approjects-warn-act-notices.static.hf.space/watch-now.html) 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 →](https://approjects-warn-act-notices.static.hf.space/api.html)

**Prefer a spreadsheet?** One formula puts the last 90 days, the last 12 months
or any single state into Google Sheets as a live range that refreshes itself —
no signup, no add-on: [the formulas, one per state →](https://approjects-warn-act-notices.static.hf.space/sheets.html)
`=IMPORTDATA("https://cdn.jsdelivr.net/gh/APVentureEngine/warn-act-notices@main/data/sheets/us-last-90-days.csv")`

**Backtesting, or citing a figure you published last month?** Today's file has
look-ahead and survivorship bias baked in: notices get amended after the fact and
some rows are later deleted. The same table as it stood on any past day since
**2026-08-30** — one immutable vintage per day, 20 so far, plus a first-appearance
index giving the first and last day every notice id was in the file — is the
[point-in-time snapshot archive](https://huggingface.co/datasets/APProjects/us-warn-act-layoffs-point-in-time-snapshots). Nobody can backfill it.

**Need one industry only?** The same filings, cut by an auditable employer-name
rule (each row keeps the rule that fired): [tech companies](https://huggingface.co/datasets/APProjects/us-tech-company-layoffs-warn-act-notices-daily)

**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.

**Not deciding today?** [Join the update list →](https://approj.gumroad.com/subscribe) — one email when a
new dataset or tier is published; nothing promotional. A state added or a column
renamed ships in the [daily release](https://github.com/APVentureEngine/warn-act-notices/releases) instead, no address
needed. The list is
shared across APProjects datasets, holds an email address only, is run by
Gumroad, and any message unsubscribes you. Rather give no address at all?
[Watch the repo's releases](https://github.com/APVentureEngine/warn-act-notices/subscription) — GitHub notifies you on
every daily republish, and a new state or changed field is in those notes the
day it lands.

**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](https://github.com/APVentureEngine/warn-act-notices/issues/new/choose). Payments are handled by Gumroad as merchant of
record, so an invoice can carry your company name.
