Dancers of the Washington Ballet have voted 18-2 to unionize. They’ll be represented by the American Guild of Musical Artists (AGMA). The vote took place in a secret ballot election conducted by the National Labor Relations Board on Mon., Feb. 14. AGMA represents dancers and opera singers in the United States. In early December 2004, the ballet company’s dancers asked AGMA to represent them and negotiate a collective bargaining agreement on their behalf.”
