LOS ANGELES (AP) — Fifty days into a strike with no end in sight, about 1,000 Hollywood writers and their supporters marched and rallied in Los Angeles for a new contract with studios that includes payment guarantees and job security. Speakers at the Writers Guild of America's WGA Strong March and Rally for a Fair Contract on Wednesday emphasized the broad support for their cause shown by other Hollywood unions — including actors in their own contract negotiations — and labor at large. “We’re all in it together, we’re all fighting the same fight, for a sustainable job in the face of corporate greed,” Adam Conover, a writer and a member of the guild’s board and its negotiating committee, told a crowd at the end of the march at the La Brea Tar Pits.
