GM replaces more than 1,000 workers with 50 robots at Detroit EV plant

General Motors has installed 50 collaborative robots, or cobots, at its Factory ZERO EV plant in Detroit, according to reporting published Sunday, setting off a labor dispute over automation at one of the company’s most visible EV facilities.

The report said the change affected more than 1,000 workers. GM has not publicly confirmed that figure in the remarks cited in the reporting, and the exact scope of the job impact remains unclear.

GM said the cobots are part of a broader rollout across its manufacturing footprint and are meant to improve safety, ergonomics and flexibility while keeping operations competitive. UAW Local 22, which represents workers at the plant, says the company is taking manpower away from employees and has filed grievances.

Factory ZERO at the center of the dispute

Factory ZERO is GM’s first fully dedicated electric vehicle assembly plant in Detroit and is represented by UAW Local 22. The plant builds the GMC HUMMER EV, Chevrolet Silverado EV, GMC Sierra EV and Cadillac Escalade IQ.

That makes the site a high-profile part of GM’s EV strategy and a sensitive place for a labor fight over automation. Any change in staffing or production methods at the plant carries outsized significance for both the company and the union.

The dispute also lands after a difficult stretch for the site. Prior coverage reported that GM had already extended a shutdown through April 13, 2026, with about 1,300 temporary layoffs amid weak EV demand.

What GM and the union say

GM spokesperson Kevin Kelly said the company has been installing cobots across its manufacturing operations and that, at Factory ZERO, the robots are intended to help improve safety and ergonomics while preserving flexibility on the line.

UAW Local 22 President James Cotton took the opposite view, saying the union believes the company is taking work away from people. The union has filed grievances against GM over the change.

The available reporting does not spell out the full grievance details, and it is not clear from the company’s public remarks whether the cobots are replacing specific tasks or supplementing workers in certain parts of the plant.

The worker-impact figure is also still an open question. The report’s claim that more than 1,000 workers were affected has not been formally confirmed by GM in the cited public statements.

Why it matters

The fight at Factory ZERO reflects a broader question facing the auto industry’s EV transition: whether automation is being used to support workers and improve plant conditions, or to reduce headcount and shift leverage away from labor.

For GM, the plant sits at the center of its EV manufacturing strategy. For UAW Local 22, it is a live test of how much control workers will have as automation expands inside a flagship facility.

What happens next may depend on how GM responds to the grievances and whether the dispute draws any formal contract or regulatory scrutiny. For now, the rollout has become the latest flash point in the company’s push to reshape production at Factory ZERO.
