General Motors has installed 50 new robot arms at its Detroit factory, sparking union backlash as 1,300 workers remain laid off. The robots, made by FANUC, will help with vehicle assembly, but union leaders argue that the company should bring back laid-off workers instead. This move is part of a larger trend of automakers automating their operations, with other companies like Hyundai and Ford also deploying robots. Why it matters: the increasing use of automation in the automotive industry could have significant implications for worker employment and wages, highlighting the need for a balance between technological advancement and social responsibility.
