Gene Maddaus Senior Media Writer With a tentative Directors Guild of America deal in hand and the Writers Guild of America on strike, SAG-AFTRA has been thrust into a bigger role than the performer’s union has played in years in the industry’s triennial labor contract negotiations. SAG-AFTRA gets its turn at the bargaining table this week, with an agenda that seeks to address the many ways that technology is changing the profession of acting. Two of the union’s top concerns — streaming residuals and artificial intelligence — are also key issues for the WGA and DGA. The performers’ guild is also uniquely focused on putting limits on “self-taped” auditions, which have become ubiquitous since the beginning of the pandemic.
