General Motors is facing backlash from labour unions after cutting more than 1,000 jobs at its main Detroit assembly plant and replacing the human workers with 50 new robot units.
After softening its EV commitments, the US automaker deployed “collaborative robots,” or cobots, at the Michigan facility. These machines now work alongside the remaining staff to attach vehicle body panels to the moving assembly line.
The automaker confirmed that the dozens of robotic units had been added to the plant as part of its broader automation strategy. The company added that the cobots are necessary to stay competitive as well as improve “safety and ergonomics” for the workers.
“We’ve been installing cobots across our manufacturing footprint as part of a broader push to bring more advanced technology into our operations,” spokesman Kevin Kelly said. “At Factory ZERO, we are implementing them alongside our team, helping improve safety and ergonomics, while keeping our operations flexible and competitive.”
Union Opposition
The decision has not gone down well with trade unions. United Auto Workers Local 22 President James Cotton said the machines are simply taking jobs from his union members.
“It’s always a concern when you see a robot coming to a plant, especially after they have laid off over a thousand people,” Cotton said. “They say it’s the wave of the future, and if that’s so, they’re taking away jobs from people.”
“From top to bottom, we’re disgusted that they have cobots in our plants,” he added.
The Financial Picture
In the first quarter of 2026, GM reported $4.25 billion in profits, up 22% from the same period the previous year. The company’s decision to automate comes amid a broader shift in the auto industry toward efficiency and cost-cutting.
GM’s move follows a trend among major manufacturers to deploy automation to reduce labour costs and increase production flexibility. However, the scale of the job cuts at the Detroit plant has drawn particular scrutiny, given the city’s historical reliance on automotive manufacturing jobs.
The Bottom Line
General Motors has replaced more than 1,000 human workers with 50 robots at its Factory ZERO assembly plant in Detroit, Michigan. The automaker said the “cobots” improve safety and competitiveness. The United Auto Workers union has condemned the move, saying the machines are taking jobs from members. GM reported a 22% profit increase in the first quarter of 2026.
