Crain’s New York Business: The labor movement has a new and unlikely champion: the staff at Gawker Media, which has voted by a margin of 3-1 to unionize under the Writers Guild of America, East. The vote marked the first time a purely digital-media operation has opted for union representation. It was also a big win for the Writers Guild, which is best known for representing film and television writers but hopes to bring other digital-media outlets under its collective-bargaining umbrella. “Online media is an industry that has grown up in a post-union age.”
