Television and radio actors who have been on strike against advertisers since May 1 are back to work today, officially ending the longest talent walkout in Hollywood history. A joint board of Screen Actors Guild (SAG) and The American Federation of Television and Radio Artists (AFTRA) members issued a statement Saturday recommending that members accept a tentative three-year contract that was reached last week with advertisers. According to SAG spokesman Greg Krizman, the vote by some 150 members of the boards of SAG and AFTRA was nearly unanimous. The proposed contract says that advertisers must agree to continue paying residuals to actors for commercials airing on network television, but are not obligated to pay actors for commercials shown on cable. The strike cost the Los Angeles-area economy an estimated $125 million in lost production, according to the Associated Press.
