NPR's Mondeleek Delbarco reports members still need to ratify the deal. The International Alliance of Theatrical Stage Employees, or IATSE, represents 50,000 below-the-line workers in Hollywood, including cinematographers, costume designers, makeup artists, hairstylists, set decorators, lighting technicians, and other craftspeople.
