Spring Hill Manufacturing, an assembly and propulsion plant, is the largest GM facility in North America with nearly 4,000 total employees. It builds the Cadillac XT5 and XT6 as well as electric LYRIQ and GMC Acadia
Moments before employees walked out in Tennessee, the UAW said it reached a tentative labour agreement with Chrysler parent Stellantis. It reached a similar deal with Ford Motor on Wednesday.
A strike at Spring Hill could cripple output at all of GM’s large pickup operations, greatly increasing the financial pain for the company.
The UAW’s walkout at the Arlington, Texas factory that builds Cadillac Escalades and Chevrolet Suburbans is costing US$200 million a week, GM said.
The UAW previously struck GM assembly plants in Missouri and Michigan as well as 18 parts distribution warehouses.
