Members of the International Alliance of Theatrical Stage Employees are striking against The Biggest Loser, an action that has shut down production on the eleventh season of the NBC reality series, the union confirmed today. In a statement, IATSE president Matthew Loeb said: “This is a top-rated prime-time television show, and the crew remains unified. The strike is the result of a unanimous decision by members of the production crew that they get a contract similar to others covering these types of productions, and we are resolute in getting it for them.” NBC referred all calls to Reveille Productions, one of the producers of Biggest Loser; a Reveille spokesperson had no comment. The network — which is currently airing the show’s tenth seasonwill debut season 11 in January.
