Covenant Aviation Security Files 1,279-Worker WARN Notice in San Francisco, Effective Nov 30

A WARN notice dated September 28, 2026 reports that Covenant Aviation Security plans to lay off 1,279 workers in San Francisco, California, with the cuts effective November 30, 2026. It is the largest recent WARN filing in the country not previously covered in this series, and one of the largest single filings recorded in California in recent weeks.

What the filing says

The notice, published through California's WARN records and tracked by Layoff Atlas, lists the following details:

• Employer: Covenant Aviation Security
• Location: San Francisco, California
• Workers affected: 1,279
• Notice date: September 28, 2026
• Effective date: November 30, 2026
• Event type: Layoff

The 63-day gap between the notice date and the effective date matches the standard WARN Act requirement of at least 60 days' advance notice for mass layoffs and plant closings. California's mini-WARN law mirrors the federal 60-day requirement.

Why this filing stands out

In the current 90-day notice window, Layoff Atlas tracks 737 WARN notices covering 67,101 reported workers nationwide (last synced October 18, 2026), with 28 notices carrying unavailable worker counts. California accounts for 15,067 of those workers — the second-highest state total after Washington's 16,855, ahead of Illinois (4,626), Texas (3,784), and Ohio (3,180).

A single 1,279-worker filing represents roughly 8.5 percent of California's entire 90-day reported total. That is what makes this notice notable: it is large enough to move the state number on its own.

Nationally, the only larger recent filing in the 100-plus-worker bracket was Gebbers Farms' 3,445-worker notice in Washington, covered earlier this month. The next-largest recent filings — FirstFruits in Washington (1,200), National Frozen Foods in Washington (439), and a Randstad/Dreyer's filing in Bakersfield, California (426) — all trail Covenant's number.

The timeline for affected workers

• September 28, 2026: WARN notice filed
• November 30, 2026: layoffs take effect

With the effective date roughly six weeks out, affected workers are inside the notice window where WARN's protections apply: pay and benefits continue through the notice period. Workers should confirm their individual separation date in writing, ask about final pay and any severance, and know that California's Employment Development Department offers rapid-response services after mass layoffs.

What WARN numbers do and don't say

A WARN filing is the employer's reported plan, not a confirmed job loss. Companies sometimes file for more workers than are ultimately let go, amend or cancel notices, or transfer workers instead of separating them. The 1,279 figure should be read as the company's stated plan as of the filing date.

The undercount runs the other way, too. Layoffs at employers with fewer than 100 workers, or smaller rounds that stay under WARN thresholds, never appear in these records — so WARN data is a floor, not a ceiling. And the 28 notices in the current window with unavailable worker counts mean the 67,101 national total is itself an undercount.

The weeks ahead

By effective date, the heaviest upcoming week is the week of November 15, with 7,781 reported workers scheduled, followed by the week of November 22 with 6,527. The Covenant Aviation Security cuts land just after that peak, effective November 30 — a reminder that large single-employer filings can reshape any given week's totals on their own.
