Gene Maddaus Senior Media Writer With one strike already underway, SAG-AFTRA announced Friday that it will seek authorization for a second strike against the major video game companies. The union said that talks on a new video game contract have reached a “stalemate,” and that the strike authorization vote is needed as leverage to win wage increases and protection from artificial intelligence. SAG-AFTRA declared a strike on July 13 against the major TV and film companies, shutting down productions around the globe.
