United Auto Workers (UAW) production employees at two Ford Motor plants and one General Motors (GM) plant have voted down a tentative contract agreement.
UAW production employees at Ford's truck plant and another assembly plant in Louisville, Kentucky, have rejected a tentative labor agreement, with 55pc voting against, according to a Facebook post on UAW Local 862's page.
Skilled trades workers have approved it with 69pc voting in favor.
The majority of Ford's UAW hourly production employees at 25 plants who have voted so far have approved of the deal, though a similar number of sites still need to vote, according to an online UAW vote tracker.
At GM's Flint, Michigan, full-size pickup truck plant, UAW Local 598 production employees voted down the tentative agreement with 52.8pc against, according to results published 10 November on Local 598's Facebook page.
At another five GM sites UAW production employees have rejected the contract, with the vast majority of GM facilities yet to vote, according to the UAW vote tracker.
The moves come weeks after the union reached tentative agreements with Ford, GM and Stellantis, temporarily ending a strike while membership reviewed the tentative agreements and voted. The strike against the three companies began on 15 September.
Ford declined to comment.
GM did not immediately reply to a request for comment.
At Stellantis only six of 38 sites have voted on the tentative agreement, with all of those approving the contract.
