FRANKFORT, Ky. (AP) — Workers at the General Motors plant in Kentucky that assembles Corvettes voted Tuesday to authorize a strike over lingering safety concerns, but a local union leader said he hopes the differences can be resolved without a walkout.

Union members voted overwhelmingly to give union leaders the green light to call a strike if necessary. About 800 union workers were eligible to vote, and more than 90 percent of those casting ballots backed the strike authorization, said Eldon Renaud, president of United Auto Workers Local 2164
