Musicians at New York’s famed Radio City Music Hall are threatening to strike over the issue of overtime pay for the venue’s popular Christmas Spectacular. (Yeah, that’s the one with the Rockettes.) A strike could jeopardize the show, which draws huge numbers of tourists and is a New York institution, but Cablevision, which owns Radio City, has issued a statement saying that it “fully expects” to reach an agreement with the musicians before the show opens for the year.
