WARN Act and Layoffs in Aerospace and Defense: What Contract Workers Should Know

Defense and aerospace layoffs rarely look like a factory closing. A federal contract goes into recompete, a program office shifts funding, or an airport security contract changes hands — and hundreds of engineers, technicians, and cleared support staff learn their jobs are at risk before anyone knows whether the work will continue. Two recent filings show the pattern.

Layoff Atlas tracks 681 WARN notices covering 61,493 workers in its 90-day window. These are reported plans, not confirmed job losses: dates move, contracts get renewed, and some layoffs are cancelled.

The GDIT pattern: six notices, 714 workers

General Dynamics Information Technology (GDIT), the IT services unit of General Dynamics, has filed six WARN notices in 2026 covering 714 workers, nearly all tied to federal contracts. The newest covers 153 workers at a Herndon, Virginia office, notice filed October 30, 2026, effective December 30, 2026 — 61 days, one over the federal minimum.

In April, GDIT filed for 87 employees in Washington, D.C., effective June 15. In June, two notices covered 236 workers in Northern Virginia — 133 in Falls Church and 103 in Arlington, tied to the F-35 Joint Program Office contract — plus a 174-worker Pentagon notice effective August 8. A 64-worker D.C. notice followed in July.

GDIT itself has said most of its notices in the last year did not end in separations — the filings are precautionary, issued while a contract outcome is uncertain. The Herndon notice is therefore conditional: 153 workers are at risk on December 30, pending contract decisions that may not be public yet.

Covenant: 1,279 aviation-security workers

The largest aerospace-adjacent filing in the current window comes from the other end of the industry. Covenant Aviation Security filed a notice on September 28, 2026 covering 1,279 workers in San Francisco, California, effective November 30, 2026 — 63 days of notice, three over the federal minimum.

One filing is about 2.1 percent of all workers in the national 90-day window and 5.8 percent of California's 22,043-worker total. Aviation security follows the same contract logic: when the contract changes, the workforce turns over with it.

The 60-day rule, in plain English

The Worker Adjustment and Retraining Notification Act requires most employers with 100 or more full-time employees to give 60 days' written notice before a plant closing or mass layoff. A plant closing shuts down a single site with 50 or more workers affected; a mass layoff is 500 or more at one site, or 50 to 499 if they are at least one-third of the site's workforce. Notice goes to affected workers, their union representative if any, the state dislocated worker unit, and the local chief elected official.

The 100-employee threshold counts company-wide; layoff thresholds are measured site by site. One employer may staff a program office, a depot, and a dozen small sites: closing one site of 60 engineers triggers WARN; cutting 60 people across a dozen small offices may not.

The contract structure adds a second complication. The prime contractor holds the federal contract, but subcontractors and staffing firms do much of the work. WARN applies to the direct employer: if the prime ends a subcontract, the subcontractor — not the prime — owes its own workers notice, and only if its own layoff meets the thresholds. Check whose name is on the notice; that employer is the one legally responsible for it.

What the numbers say right now

Virginia, where GDIT is concentrated, recorded 68 notices covering 8,477 workers in 2026; its archive holds 2,196 notices reporting 255,451 workers. In the 90-day window Virginia is third with 2,556 workers, behind California (22,043) and Washington (17,333); Maryland (2,547) and Texas (2,419) follow.

The heaviest week ahead is November 22 (6,614 workers), then November 29 (6,202). December 6 is the lightest at 857, before 5,310 the week of December 13 and 2,551 the week of December 20. GDIT's December 30 date falls just past the six-week window the homepage shows.

What to do when a notice lands

First, read the notice: the effective date, whether the layoff is permanent or temporary, and which employer filed it. Unemployment and severance clocks run from the effective date.

Second, ask about the contract: is it being renewed, extended, or awarded to another company? If the work continues under a new prime, some workers may be hired by the incoming contractor — ask directly rather than assuming.

Third, check your clearance. It generally needs a sponsoring employer, so ask your facility security officer what happens to it after separation and how long it stays current.

Fourth, separate WARN from severance. A WARN violator can owe back pay and benefits for each day of notice it failed to give, up to 60 days. Severance is separate — sometimes contractual, sometimes offered for signing a release that can waive a WARN claim, so read any separation agreement before signing. Enforcement is private: the federal government does not bring WARN cases. If your employer cut more than 50 people at your site with less than 60 days' notice, talk to an employment lawyer — many review WARN claims at no upfront cost.

Defense layoffs will keep arriving on contract calendars. Knowing whether a notice is precautionary or final — and who owes you the warning — is the difference between 60 days of warning and none.
