“Facing a stubborn impasse with its dancers over labor issues, the Washington Ballet has canceled all remaining performances of The Nutcracker, which was to have run through Dec. 24 at the Warner Theatre.” The company and its dancers disagreed over whether the dispute, which had already led several performances to be canceled, was a strike or a lockout. The head of the dancers’ union was shocked by the cancellation of the entire, and accused the company of having no interest in reaching an agreement.
