“After a disappointing holiday Nutcracker run, Boston Ballet has cut the salaries of virtually all its employees, with some workers taking short, unpaid leaves. The move is part of an expense-cutting plan meant to keep Boston Ballet on track for a balanced annual budget.” The company’s holiday struggles were due in large part to increased competition from the big-budget Radio City Christmas Spectacular, which forced Boston Ballet to move its Nutcracker to a much smaller theater. The company is assuring its employees that no one will be laid off.
