M.M.D. Files a 148-Worker WARN Layoff Notice for Kenosha, Wisconsin, Effective December 31, 2026

A new WARN filing in Wisconsin puts 148 workers on the layoff calendar for the last day of 2026. M.M.D. filed a layoff notice covering its Kenosha, Wisconsin, location, with an effective date of December 31, 2026, according to the Layoff Atlas registry of WARN notices. The notice is dated October 29, 2026, giving 63 days between the notice date and the effective date — just over the 60-day advance notice the federal WARN Act generally requires.

The filing is recorded as a layoff, not a closure, and it comes from Wisconsin's official source, the state Department of Workforce Development. It is the newest official Wisconsin notice date in the registry.

The filing in detail

The facts as recorded are straightforward:

• Employer: M.M.D.
• Location: Kenosha, Wisconsin
• Workers affected: 148
• Notice date: October 29, 2026
• Effective date: December 31, 2026
• Event type: Layoff
• Source: Wisconsin Department of Workforce Development, via the official state record

The 63-day gap between notice and effective date matters because the WARN Act's headline rule is 60 days' advance notice for qualifying plant closings and mass layoffs. A 63-day window clears that bar on its face. That said, the registry records the dates as filed; it does not adjudicate whether any particular filing complied with the law, and notice periods alone do not settle compliance questions, which can turn on the size of the employer, the number of workers at a single site, and the exceptions in the statute.

M.M.D. is the largest fresh filing on the national homepage. The next-largest recent dated filings are far smaller: Dexter Axle's 51-worker filing in Elkhart, Indiana, and Family Endeavors' 27-worker Maryland filing, both also effective December 31, 2026.

Wisconsin in 2026

Wisconsin's WARN picture in 2026 has been comparatively quiet. The state's imported archive holds 610 non-cancelled notices reporting 60,399 workers in total, but only 55 of those notices, covering 4,398 workers, fall in 2026. For comparison, Wisconsin recorded 62 notices and 4,791 workers in 2025, and 94 notices and 6,860 workers in 2024. The 2026 pace is running below both prior years.

Within the last 365 days, the archive contains 55 eligible official Wisconsin filings reporting 4,604 workers. Seven Wisconsin notices have future effective dates, and the M.M.D. filing is one of them. Recent Wisconsin filings behind it include UMOS, a 44-worker Milwaukee layoff effective December 31, 2026, and Maynard Steel Casting Company and Maynard Alloy Casting, a 77-worker Milwaukee closure effective December 4, 2026.

One caution about Wisconsin's numbers: the registry notes that its totals cover imported records only, and that grouped company names do not establish ownership. The M.M.D. name is recorded exactly as it appears in the filing, and the registry does not expand the abbreviation or attribute the filing to a parent company.

December 31 keeps stacking up

The effective date is part of a pattern worth noting. December 31, 2026, has become one of the most crowded single dates on the WARN calendar, with filings from several states and employers landing on the same day — including the Starbucks SeaTac closure, the Washington Post's Springfield filing, and now M.M.D. in Kenosha, Dexter Axle in Elkhart, and Family Endeavors in Maryland. Year-end effective dates are common in WARN data, since employers often schedule workforce changes around the turn of the calendar year, but the clustering means a large number of workers across the country share the same nominal last day.

These are reported plans, not confirmed job losses. Some filings are later amended, postponed, or cancelled.

The national picture

Nationally, the Layoff Atlas registry currently shows 685 notices covering 66,703 reported workers in its 90-day notice window, with 28 worker counts unavailable. California leads the state ranking with 17,715 reported workers, followed by Washington with 17,361, Illinois with 4,385, Texas with 3,280, and Georgia with 2,492.

The upcoming weeks remain heavy: 4,394 workers in the week of October 31, 4,326 in the week of November 7, a peak of 8,453 in the week of November 14, 6,925 in the week of November 21, 5,937 in the week of November 28, and 846 in the week of December 5. The M.M.D. filing falls outside that six-week window, on the final day of the year.

How to read this notice

If you work at the Kenosha location or follow Wisconsin layoffs, the useful facts are the ones in the filing itself: 148 workers, a layoff (not a closure), notice given October 29, 2026, and an effective date of December 31, 2026. Workers covered by a WARN notice are generally entitled to the notice itself, not to severance — severance depends on employer policy, contracts, or collective bargaining agreements, not on the WARN Act.

WARN coverage is also not a census of layoffs. Smaller layoffs often fall below the federal thresholds, and missing source coverage is not the same as zero layoffs. Wisconsin's official feed is connected and current — its source check is dated October 31, 2026 — so this filing appears promptly.

For now, the Kenosha filing stands as Wisconsin's newest official WARN notice and the largest in the latest national batch: 148 workers, 63 days' notice, and an effective date on the last day of 2026.
