“Dancers with Pittsburgh Ballet Theatre handed out leaflets before performances of ‘Cleopatra’ last week because they wanted ballet patrons to know about PBT’s proposals to reduce rehearsal time and increase the number of student performers, a union representative for the dancers said yesterday.” PBT dancers have been at an impasse with management over the details of a new contract. The issue of student performers seems to be the biggest sticking point, with dancers fearing that they could be gradually pushed out of PBT productions in favor of cheaper student performers eager for professional experience.
