General Motors workers at the Spring Hill, Tenn. auto assembly plant went on strike this morning, joining GM workers in a nationwide walkout. It happened as labor negotiations between GM and the United Auto Workers Union broke down.
Dozens of picketing union members gathered outside the plant's south gate after the 10 a.m. deadline set by the union passed.
A steady stream of vehicles began driving out of the plant, with workers honking their horns and waving in support.
A handful of cars were driving into the plant. Union officials said those were mostly contractors going back in to retrieve their tools.
The strike comes after about 2,400 of the plant's nearly 4,700 workers were laid off in April for 18 months while the former Saturn plant is retooled to produce other GM vehicles.
