LOS ANGELES (AP) -- The Screen Actors Guild negotiating committee has called for its board to support a strike authorization vote. The committee adopted a motion Wednesday calling for the vote, saying it "is necessary to overcome the employers' intransigence." Contract talks dealing with prime-time TV shows and movies have been at a standstill since the last contract expired June 30. Actors have been working under the terms of the old deal since then. A strike authorization vote would need the approval of 75 percent of the guild's some 120,000 members.
