Dissension within the Screen Actors Guild over the bargaining strategy of its leaders has reached the point that an effort has been launched to remove the entire negotiating committee and replace the members with a less obstreperous group, the Los Angeles Times reported today (Wednesday). At a board meeting on January 12, members of the dissident group are expected to call for disbanding the negotiating committee, then jump-start negotiations with the Alliance of Motion Picture and television, the Times said, probably by abandoning the union's demand for higher new media payments in exchange for additional pay increases.
