New York Times: The news website ThinkProgress said that it plans to unionize with the Writers Guild of America, East, becoming the latest digital media outlet to organize in recent months seeking better pay and working conditions. ThinkProgress will join the websites Gawker, Vice and Salon, which have recently organized with the Writers Guild of America, East, and the American arm of the British newspaper the Guardian, which has done so with the NewsGuild-CWA, as part of an expanding movement.
