Comcast has filed another WARN notice in California, covering 82 workers in Livermore, effective December 31, 2026. Notice was given on October 29, 2026 — 63 days ahead, just over the 60-day notice period the federal WARN Act requires. The filing is official, published by the California Employment Development Department (EDD).

It is the fourth Comcast WARN filing in the registry, bringing the company's reported total to 994 workers across four states — three of them effective December 31, 2026.

The filing, in brief

  • Employer: Comcast
  • Location: Livermore, California
  • Workers affected: 82
  • Event type: Layoff
  • Notice date: October 29, 2026
  • Effective date: December 31, 2026
  • Notice period: 63 days
  • Source: California EDD, via the Layoff Atlas registry

Livermore sits in Alameda County, in the East Bay. The event is listed as a layoff, not a closure, so the site itself is not recorded as shutting down.

A fourth filing in a growing cluster

The Livermore notice does not stand alone. Comcast now has four WARN filings in the registry:

  • Philadelphia, Pennsylvania — 634 workers, effective December 31, 2026, at the Comcast Technology Center. No notice date was published, so no notice period can be calculated.
  • Washington, statewide — 159 workers, effective December 31, 2026, with notice given October 29, 2026 — a 63-day notice period.
  • New Jersey, statewide — 119 workers, effective January 27, 2027. No notice date was published.
  • Livermore, California — 82 workers, effective December 31, 2026, with notice given October 29, 2026 — a 63-day notice period.

That adds up to 994 reported workers. The California and Washington filings share the same notice date, October 29, which suggests they were filed as part of the same round of decisions. December 31 is the effective date for three of the four, and it was already the most crowded single effective date on the calendar: an October 31 count put 798 workers across eight filings on that date, with more added since. The New Jersey filing is the only one of the four that falls in the new year.

California in the national picture

In the 90-day window, California accounts for 20,812 of the 64,282 reported workers nationwide — about one in three. Washington is second at 17,411. Together the two states hold nearly 60 percent of all reported workers in the window.

California's archive is the largest in the country, and 2026 is already a heavy year: 1,229 notices reporting 67,829 workers, with 145 notices still carrying future effective dates. Over the last 365 days, the state published 1,315 official filings reporting 72,658 workers, the newest dated November 2, 2026.

The Livermore filing came in the same late-October batch as Danone USA's 135-worker closure in Chatsworth, iLEAD Lancaster's 119-worker layoff, Roundabout Entertainment's 81-worker closure in Burbank, Community Tree Service's 163-worker layoff in Pajaro, and the 1,605-worker AEG Management layoff in Oakland. It was the largest filing from that batch still unexamined.

The calendar around December 31

The six weeks ahead hold 30,444 scheduled workers: 4,155 in the week of November 7, 8,510 in the week of November 14, 6,925 in the week of November 21, 6,063 in the week of November 28, 1,036 in the week of December 5, and 3,755 in the week of December 12. The week of November 14 remains the heaviest single week on the calendar.

December 31 falls just after that six-week window closes, which makes it easy to miss. But the filings landing on that one date — including the three Comcast filings, the 1,605-worker AEG Management layoff in Oakland, and the 368-worker Davey Tree cluster across ten California sites — add up to one of the largest single-day totals in the registry.

Reading the number

First, 82 workers at one site clears both thresholds that matter: the federal WARN Act's 50-worker mass-layoff trigger and California's Cal-WARN threshold, which also starts at 50. That is why a notice was required at all.

Second, 63 days is only just above the 60-day federal floor — and California's Cal-WARN law also requires 60 days — so the filing meets both with three days to spare.

Third, these are reported plans, not confirmed job losses. WARN figures describe what an employer told a state agency it plans to do, and plans can change — a filing can be postponed, reduced, or cancelled. The national totals also exclude the 28 notices in the current 90-day window where no worker count was published, and coverage varies by state, so the registry is a floor on layoff activity, not a census of it.

What affected workers can do

Workers at the Livermore site have just under eight weeks until the effective date. Check the filing details with the California EDD to confirm the site and dates. Ask the employer in writing about severance, extended benefits, or transfers — none are required by the WARN Act, but many employers offer them and terms are often negotiable during the notice period. Contact California's Rapid Response team through the EDD for free help with unemployment filing, retraining, and job search, and keep copies of the notice, pay records, and any separation agreement.

The Livermore filing is a reminder that the December 31 cluster keeps growing, and that the year's largest layoff date is still more than seven weeks away.
