It’s labor contract resolved and its budget reduced, Washington Ballet announces a new pared-down season. “A long-running labor dispute forced the cancellation of nearly half of December’s run of ‘The Nutcracker,’ which the ballet company said resulted in a substantial loss of ticket revenue that in turn led to the scrapping of other scheduled performances and the laying off of the dancers. A tentative agreement on a first-ever employment contract with the American Guild of Musical Artists, the dancers’ union, was reached this month. With the ballet back in business, we’ve made a decision to invest in the artistic product.”
