Fiat Chrysler Automobiles (FCHA.MI) (FCAU.N) will get the first shot at setting a pattern for wages and benefits for more than 140,000 unionized factory workers at the Detroit Three automakers, the company and the United Auto Workers union said Sunday. The UAW did not elaborate on its decision to choose FCA to set the pattern for new master contracts it will later negotiate with General Motors Co (GM.N) and Ford Motor Co (F.N).
