UMOS Files 44-Worker Milwaukee WARN Notice for December 31

UMOS has filed a WARN notice in Wisconsin covering 44 workers in Milwaukee, with an effective date of December 31, 2026. The notice was filed on October 28, 2026, giving workers 64 days of advance notice — just over the 60-day minimum required under the federal WARN Act for qualifying mass layoffs and plant closures.

The filing is recorded as a layoff, not a closure, and it is sourced to the Wisconsin Department of Workforce Development. It is also the newest official Wisconsin notice date in the Layoff Atlas archive, which makes it the freshest Wisconsin filing on the tracker this week.

The filing at a glance

  • Employer: UMOS
  • Location: Milwaukee, Wisconsin
  • Workers affected: 44
  • Notice date: October 28, 2026
  • Effective date: December 31, 2026
  • Notice period: 64 days
  • Type: Layoff
  • Source: Wisconsin Department of Workforce Development

These figures come from the WARN notice as filed and tracked by Layoff Atlas. They describe reported plans, not confirmed job losses. Companies sometimes revise, delay, or cancel planned layoffs after filing, and final headcounts can differ from the number in the original notice.

Why the timing matters

The 64-day gap between the notice date and the effective date is slightly longer than the federal WARN Act's 60-day requirement. The WARN Act — the Worker Adjustment and Retraining Notification Act — requires employers with 100 or more full-time workers to give at least 60 days' written notice before a plant closing or mass layoff affecting a qualifying number of employees.

Wisconsin also has its own mini-WARN law, with its own employer and layoff thresholds that differ from the federal rules. The practical point for affected workers is the same under either law: the notice period is meant to give people time to look for new work, seek retraining, and connect with state workforce services before the effective date arrives.

December 31 is also a notable effective date. It falls on the last day of the calendar year, and it is turning into a small year-end cluster in the WARN data: Comcast's 159-worker statewide Washington filing is also effective December 31, as is a smaller 6-worker Maryland filing from Bull, Shamz-Azar, Larkin & Cohen. Year-end effective dates are worth watching because they can coincide with budget cycles, contract changes, and seasonal slowdowns.

Wisconsin in the national picture

Wisconsin's WARN archive holds 609 non-cancelled imported notices reporting 60,251 workers affected in total. In 2026 alone, the state has recorded 54 notices covering 4,250 workers, and seven notices currently have future effective dates. Over the last 365 days, the imported archive contains 54 eligible official Wisconsin filings reporting 4,456 workers, with no worker counts unavailable in that official set.

The UMOS filing sits alongside several other recent Wisconsin notices with December effective dates, including a 77-worker Maynard Steel Casting closure in Milwaukee effective December 4, a 47-worker Bank First layoff in Wausau effective December 4, and a 68-worker Foremost Farms USA closure in Marshfield effective December 15. Together, they show a state calendar that is weighted toward the end of the year, even though Wisconsin is not among the heaviest states nationally.

Nationally, Wisconsin's totals are modest compared with the current leaders. California leads the 90-day window with 17,715 reported workers, followed by Washington with 17,361, Illinois with 4,385, Texas with 3,280, and Georgia with 2,492. Wisconsin's story is less about volume and more about the steady drumbeat of mid-size filings like this one.

The national backdrop

Across the United States, Layoff Atlas currently tracks 678 WARN notices covering 65,927 reported workers in its 90-day window, with 29 notices where the worker count is unavailable. Those totals move daily as new notices are filed and older ones roll out of the window.

The upcoming calendar shows how concentrated the year-end layoffs are. The six upcoming effective weeks currently total 33,811 reported workers: 7,049 in the week of October 30, 3,302 in the week of November 6, 8,793 in the week of November 13, 7,181 in the week of November 20, 5,778 in the week of November 27, and 1,708 in the week of December 4. The week of November 13 is currently the heaviest upcoming week, and the December 31 filings, including UMOS, fall just beyond that six-week window.

What happens next

For the 44 workers covered by the UMOS notice, the next step is the period between now and December 31. Workers covered by a WARN notice can typically contact their state's workforce agency for help with job search, unemployment benefits, and retraining programs. In Wisconsin, the Department of Workforce Development and its local job centers are the usual first points of contact.

It is also worth watching whether the filing is amended. WARN notices are sometimes updated with revised worker counts or effective dates, and Layoff Atlas updates its records as new filings arrive. If UMOS revises this notice, the updated figures will replace the 44-worker count in the tracker.

For everyone else, the filing is one more data point in a year-end pattern: employers filing notices in late October for effective dates clustered around the end of the year. Whether that pattern holds through December will depend on the notices filed in the coming weeks.
