General Motors is laying off 1,300 workers at Factory Zero, its electric-vehicle assembly plant in Detroit-Hamtramck, Michigan, The Detroit News reported.

The reduction is one of the largest single-plant workforce cuts GM has made at an EV-dedicated facility since it began building battery-electric trucks there. Factory Zero assembles the GMC Hummer EV pickup and SUV and the Chevrolet Silverado EV, models that sit at the high end of GM's electric truck lineup.

What do the layoffs signal?

The cut comes as GM, like other Detroit automakers, adjusts EV output to demand that has run below earlier internal forecasts. Factory Zero was rebuilt at a reported investment of roughly $2.2 billion and retooled to become GM's first fully electric assembly plant, with the company at one point citing capacity of up to 270,000 trucks a year at full ramp.

Workforce reductions at a flagship EV plant matter beyond the headcount. They mark the gap between capacity plans drawn up during the 2021-2022 EV investment wave and the slower order books automakers face in 2024-2025. Suppliers tied to the plant's build rate — from battery-cell partners to tier-one truck-component vendors — will read the layoff number as a signal to recheck their own volume assumptions.

Who is affected?

The 1,300 workers losing jobs represent a substantial share of the hourly and salaried staff GM had added as it ramped Hummer EV and Silverado EV production. United Auto Workers representation at the plant gives the cuts contractual and political weight in Michigan, where Factory Zero sits inside Detroit's city boundary.

No details were immediately available on which shifts, departments or vehicle lines the reductions target, or on the timing of the layoffs.

What to watch next

Watch for GM's confirmation of the layoff timing and whether production schedules for the Silverado EV and Hummer EV change alongside the workforce cut. The next capacity milestone to track is Factory Zero's actual annual output against the plant's stated ramp targets — and whether GM revises its broader EV capacity plans in upcoming guidance.
