David Robb Labor EditorThe board of directors SAG-AFTRA’s Los Angeles Local voted overwhelmingly Tuesday – strictly along the guild’s fractious party lines – to oppose ratification of the union’s new film and TV contract. The local is the union’s largest, representing just over 50% of the entire membership.Local board members voted 29-13 (69%-31%) to oppose ratification, almost exactly the reverse of the national board, which late last month voted 67.6%-32.4% to approve the contract.
