The United Auto Workers (UAW) has announced the expansion of its strike at Ford and General Motors to include another 7,000 workers, bringing the total number of striking workers to over 50,000. The strike is in response to the automakers' refusal to make meaningful progress in negotiations over wages, job security, and health care benefits. GM has estimated that it has lost $2 billion in profits since the strike began, and the union is hoping that the additional 7,000 workers will help to pressure the automakers into making a deal.
