AEG Management Oakland has filed a WARN notice covering 1,605 workers in Oakland, California, effective December 31, 2026. The notice was dated October 29, 2026, and is recorded as a layoff filing sourced from the California Employment Development Department. It is the largest recent California filing visible in Layoff Atlas data.

These are reported plans, not confirmed job losses. A WARN filing is an advance notice of a qualifying layoff or closure; the number in the filing is the number of workers the employer reported as affected, not a count of people who have already lost their jobs.

What the filing says

According to the California record:

  • Employer name as listed: AEG Management Oakland
  • Location: Oakland, California
  • Workers reported: 1,605
  • Event type: layoff
  • Notice date: October 29, 2026
  • Effective date: December 31, 2026
  • Source: California Employment Development Department, via Layoff Atlas

Layoff Atlas notes that grouped company names do not establish ownership, so the filing name should be read as the name on the notice, not as a verified statement about a parent company or a specific venue. The filing does not explain the reason for the layoff, and this article does not add one. Workers at the site should rely on the notice they receive directly from their employer for their own effective date and benefits information.

A 63-day notice period

The gap between the notice date and the effective date is 63 days: from October 29 to December 31, 2026. That sits just above the 60-day advance-notice period that the federal WARN Act generally requires for qualifying mass layoffs and plant closings.

The comparison is limited. The federal law sets a floor, not a schedule, and it has exceptions and thresholds that depend on the employer, the number of workers, and the circumstances. California also has its own mini-WARN law, Cal-WARN, which can apply more broadly. This article does not claim the filing complies with either law. What the dates do show is that affected workers received roughly two months of advance warning — the practical purpose of the notice system.

Why December 31 keeps appearing

December 31, 2026 is a strikingly common effective date in the current data. Several other recent filings share it, including Chick-fil-A in Oxnard, California (87 workers, notice November 2), GEICO in Lakeland, Florida (114 workers, notice November 2), International Automotive Components Group in Cottondale, Alabama (83 workers, notice November 2), and the Comcast Technology Center filing in Philadelphia, Pennsylvania (634 workers, undated import). The shared date reflects year-end clustering: employers often schedule workforce changes at calendar boundaries.

Layoff Atlas's upcoming-by-week figures show 3,224 workers effective in the week of November 4, 6,224 in the week of November 11, 5,939 in the week of November 18, and 9,858 in the week of November 25, before falling to 1,890 in the week of December 2 and 1,746 in the week of December 9. The AEG workers fall beyond that six-week window, so the year-end picture is heavier than the next-six-weeks picture suggests.

California in the national picture

California dominates the current national totals. In the 90-day notice window, Layoff Atlas reports 685 notices covering 65,371 workers nationally, with 26 counts unavailable. California accounts for 21,216 of those workers, ahead of Washington at 17,320, Illinois at 3,649, Texas at 2,863, and Maryland at 2,395. The AEG filing alone represents about 7.6 percent of California's 90-day worker total, which shows how much a single large filing can move a state's numbers.

The longer California archive puts the filing in perspective. California has 17,657 non-cancelled imported WARN notices reporting 1,459,656 workers affected, with 147 notices carrying future effective dates. In 2026 alone, the state has 1,229 notices covering 67,829 workers. Against that history, a single 1,605-worker filing is large but not unprecedented. Again, these are reported plans, not confirmed job losses, and the archive counts notices, not unique people.

How to read a filing this size

Three cautions apply to a filing this size.

First, the worker count is the employer's reported figure at the time of filing. Filings are sometimes amended, and effective dates sometimes shift. The registry is a snapshot of notices, not a final employment record.

Second, a layoff filing is not a closure filing. The California record classifies this one as a layoff, not a closure, which means the notice does not by itself say a site is shutting down. It says 1,605 workers are reported as affected by a layoff effective December 31.

Third, state totals are not a ranking of economic health. Coverage and reporting rules vary by state, and California's large totals partly reflect its size and thorough reporting. A state with a smaller total may simply report less. Layoff Atlas warns that missing coverage is not zero layoffs, and that WARN coverage is not a census of layoffs.

The bottom line

The AEG Management Oakland filing is the largest recent California WARN notice in the current data: 1,605 workers, notice October 29, 2026, effective December 31, 2026. It lands in a year-end cluster of effective dates, in a state accounting for roughly a third of the nation's reported WARN workers in the 90-day window. Like every filing in this series, it describes reported plans, not confirmed job losses.
