Despite reports earlier today that NBC’s “Christmas In Rockefeller Center” broadcast may not air as scheduled on Wednesday night due to a labor dispute, an insider tells EW.com that the show will go on. Earlier today, the union representing 3000 producers, technicians, and writers employed by NBC threatened to strike the event over “stalled negotiations” for a new contract. The previous agreement expired last March. NBC responded with a statement criticizing the union for canceling recent meetings to continue discussions. Yet despite the press-release salvos, an insider says the event will take place “without incident.” This year’s Rockefeller Center festivities in New York–which, as always, is highlighted by the lighting of a towering Christmas tree–will be hosted by Jane Krakowski (30 Rock) and Zachary Levi (Chuck).
