The Broadway stagehands’ union, Local One, and the group that represents the theaters will begin negotiations again in two weeks, with meeting dates scheduled on November 7, 8, and 9, a union source and the executive director of the League of American Theaters and Producers, Charlotte St. Martin, confirmed. The two parties have been at odds since October 9 when they both presented what they said were final contract offers. Last Monday, the theaters began imposing portions of their work contract on the stagehands.
