Five days ago, December 31, 2026 looked like a modest cluster on the layoff calendar: three WARN filings, 422 workers, all sharing the last day of the year as their effective date. Since then, five more filings have landed on the same date, and the cluster has nearly doubled. Eight filings now list December 31 as their effective date, covering 798 reported workers across seven states.
These are reported plans, not confirmed job losses. A WARN filing is an employer's advance notice of a planned layoff or closure, and plans can change before the effective date. But the growth of this one-date cluster is still a useful signal: when several unrelated employers pick the same effective date, the calendar itself becomes part of the story.
The eight filings, in order of size
The largest December 31 filing is Pep Boys Manny Moe & Jack, with 169 workers at its Bala Cynwyd, Pennsylvania corporate offices. The notice, dated September 23, 2026, followed Mavis Tire's acquisition of the company and a reorganisation of corporate support services. Its listed effective date is December 31, with phases extending into February.
Next is Comcast, with a 159-worker statewide filing in Washington, noticed on October 29, 2026 — a 63-day notice period. Then comes The Washington Post, with 118 workers at its Springfield, Virginia operation, noticed on October 7, 2026.
The remaining five filings are smaller but spread widely. Sealy Mattress Manufacturing filed a 114-worker closure notice for Trinity, North Carolina, noticed on October 23, 2026. Starbucks filed a 135-worker closure notice for SeaTac, Washington, noticed on October 23, 2026. Acme Brick filed a 53-worker notice for Montgomery, Alabama, noticed on October 26, 2026. UMOS filed a 44-worker layoff notice for Milwaukee, Wisconsin, noticed on October 28, 2026. And Bull, Shamz-Azar, Larkin & Cohen filed a 6-worker notice for Bethesda, Maryland, noticed on October 29, 2026.
Together: 169 + 159 + 135 + 118 + 114 + 53 + 44 + 6 = 798 workers.
What changed since October 25
On October 25, the cluster stood at 422 workers across three filings: Starbucks (135), Pep Boys (169), and The Washington Post (118). The five filings added since then — Sealy, Acme Brick, Comcast, UMOS, and Bull — contribute 376 workers, an increase of about 89 percent in less than a week.
That pace is worth noting because December 31 is still two months away. Under the federal WARN Act, employers generally must give 60 days' notice, so filings with a December 31 effective date could keep arriving into late October and, for employers giving longer notice, well beyond that. The cluster is not closed; it is a running total, and it will probably grow again before the year ends.
For proportion: the December 20 cluster — Dreyer's Grand Ice Cream (803 workers in Howard County, Maryland), DSquared Hospitality (83 in Bellevue, Washington), Republic Amusements (48 in Camp Hill, Pennsylvania), plus a 92-worker Safeway filing in Richmond, California — remains larger on a single date.
Why so many employers land on December 31
No filing states a reason for picking December 31, and this article does not guess at any single employer's motive. But the date itself explains part of the pattern: it is the last day of the calendar year, a natural boundary for budgets, contracts, and corporate reorganisations. Employers planning a year-end change tend to land on the same date for administrative reasons, even when their decisions have nothing to do with one another.
Most were noticed in late October, giving roughly 60 to 69 days' notice — close to the federal minimum, and consistent with employers working backwards from a year-end target.
The national backdrop
The December 31 cluster sits inside a busy national picture. Layoff Atlas currently holds 679 notices covering 66,050 reported workers in its 90-day notice window, with another 29 notices carrying no worker count. California (17,715 workers) and Washington (17,361) lead the state ranking, followed by Illinois (4,385), Texas (3,280), and Georgia (2,492).
The upcoming weeks remain heavy. The six-week calendar from October 30 through December 4 totals 33,811 workers, led by the week of November 13 (8,793) and the week of November 20 (7,181). Against that backdrop, the 798 workers on December 31 are a small slice — about 1.2 percent of the 90-day window total — but they are concentrated on a single day, which is what makes them visible.
How to read the December 31 number
If your own notice lists December 31, the cluster total is context, not a verdict on your situation. What matters for you is your own filing: whether the layoff is permanent or temporary, whether it is phased, and what your state offers in Rapid Response help, unemployment benefits, and retraining. A year-end effective date can also affect benefit timing and tax-year planning, so it is worth checking those details early rather than in December.
For everyone else, the cluster is a checkpoint. When December 31 arrives, compare the scheduled 798 against what actually takes effect. The gap between planned and actual is one of the most informative numbers in layoff data, and it is only visible if someone records the plan first.
