General Motors ( GM), Chrysler and Ford ( F) may get 10,100 United Auto Workers union members to accept buyouts after the elimination this year of benefits related to job security and unemployment pay, a report says. GM may buy out 5,000 workers and Chrysler may buy out about 3,000, Bloomberg reports, citing people familiar with the matter. GM's buyout ends Tuesday, and Chrysler's ends Friday. Ford may get 2,100 to leave with an offer starting April 1, Barclays Capital estimates, Bloomberg reports. The U.S. automakers are trying to get as many of their 132,600 UAW members as possible to leave to help cut labor costs to the level of non-union workers at Japanese-owned U.S. plants, the report says. The union agreed in 2007 to let automakers cut retirement benefits for new hires and pay them half as much as current employees. GM and Chrysler are negotiating with the UAW for contract concessions that are required by the terms of government loans they received. Together, GM and Chrysler have accepted $17.4 billion and say they need up to $21.6 billion more. President Barack Obama's auto task force has set a deadline of March 31 for progress in restructuring plans for the automakers. Spokesmen for GM, Chrysler and the UAW declined to comment on the progress on buyouts, according to Bloomberg. GM and Chrysler have reached tentative deals with the UAW on changes that will help the automakers become more competitive, but no details have been announced.
