WARN Act and Layoffs in Energy — What Oil, Gas, and Power Workers Should Know

Energy layoffs rarely look like factory closures. A drilling rig finishes its contract, a well is completed, a refinery unit is idled — and the crew disperses. That shape is why the WARN Act captures energy layoffs unevenly.

As of November 14, 2026, Layoff Atlas tracks 681 notices covering 61,493 reported workers in the 90-day window, with 29 worker counts unavailable. Texas, the country's largest energy state, ranks fifth nationally with 2,419 reported workers. The weeks ahead are heavy: 7,359 workers effective the week of November 14, 6,925 the week of November 21, and 6,063 the week of November 28.

The filings behind the story

• Ensco Offshore, DS-18 drilling rig, Louisiana — 75 workers. Notice December 5, 2025, effective February 10, 2026. A rig is a worksite that moves, and this filing shows WARN does reach offshore crews when the thresholds are met.
• Hess, Minot, North Dakota — 111 workers. Notice July 21, 2025, via the state's Job Service.
• Keystone Tower Systems, Pampa, Texas — 79 workers. Notice September 4, 2026, effective November 2, 2026. Keystone builds wind-turbine towers — the renewable side of the energy workforce, under the same notice rules as a drilling contractor.
• PosiGen Developer, St. Rose, Louisiana — 166 workers. A solar developer's filing, effective August 25, 2025; the record lists notice and effective date on the same day.
• Westlake, Lake Charles, Louisiana — 121 workers. Notice December 15, 2025, effective February 14, 2026. A petrochemical filing from the Lake Charles hub.

Then there is the 2020 cluster. When oil prices collapsed in spring 2020 — West Texas Intermediate briefly went negative in April — North Dakota's filings spiked: Liberty Oilfield Services, Williston, 204 workers; PerfX Wire Services, Williston and Minot, 130 each; BJ Services, Dickinson, 122; Calfrac Well Services, Williston, 83. Five filings, about 669 workers — nearly half of North Dakota's whole 2020 archive of 15 notices and 1,560 workers.

Why most energy layoffs never appear in WARN data

Four features of the law explain the quiet.

The 100-employee threshold. Federal WARN applies only to employers with 100 or more full-time employees. Oilfield services run on small crews and subcontractors, so a 40-person wireline crew laid off when a rig contract ends never triggers a filing.

Contractors often do not count. A worker employed by a staffing firm or a subcontractor is generally that firm's employee, not the operator's. When an operator cancels a drilling program, the layoffs land on a dozen small service companies, each below the threshold.

The temporary-project exception. WARN does not require notice when a closing is due to the completion of a particular project or undertaking (29 U.S.C. 2103(1)). The end of a drilling contract or the completion of a well is the textbook case. Many end-of-contract reductions are never filed for that reason.

The unforeseeable-circumstances exception. A sudden price crash can qualify as unforeseeable business circumstances, which shortens or eliminates the notice requirement. The 2020 filings were made anyway, but a crash does not guarantee 60 days' warning.

The states with no backup law

Federal WARN is the only notice law in the big energy states. Texas, North Dakota, Oklahoma, and Louisiana have no state mini-WARN law — no lower threshold, no longer notice period. A worker in those states gets the federal minimum or nothing. California's Cal-WARN applies at 75 employees instead of 100; New Jersey requires 90 days' notice. Where you work decides how much warning the law requires.

The blind spot has a geographic signature: Oklahoma, an oil state, holds 220 notices in the Layoff Atlas archive — and not one carries a usable worker count. North Dakota recorded just one notice, 47 workers, in 2026. Missing coverage is not zero layoffs.

What energy workers should know

• You are owed 60 days' notice if the thresholds are met — your employer has 100+ full-time employees, and the layoff is a plant closing of 50+ workers, a mass layoff of 500+, or 50–499 workers if that is at least a third of the site's workforce.
• A rig, a refinery unit, and a wind-tower plant can each be a "single site of employment." The test turns on where workers are assigned, not where the company is headquartered.
• "Temporary" and "project complete" are arguments, not facts. If your employer cites the temporary-project exception, the question is whether the work really ended as a defined project or was an ongoing operation cut short — a distinction worth a second opinion.
• A price crash does not erase the notice duty by itself. The unforeseeable-circumstances exception is narrow, and employers relying on it must still give as much notice as practicable.
• Check whether your employer filed. State labor agencies publish WARN lists, and Layoff Atlas tracks filings by notice and effective date. If no notice was filed and you believe one was owed, the remedy under the Act is back pay and benefits for up to 60 days.

Energy will keep producing WARN filings in bursts — a price shock, a contract round, a plant turnaround — with long quiet stretches between them. The registry catches the biggest employers and misses the small crews and subcontractors who do much of the work.

These are reported plans, not confirmed job losses: workers can be rehired, dates can shift, and some notices are withdrawn.
