Adjuncts at Duquesne University’s McAnulty College and Graduate School of Liberal Arts have voted 50 to 9 to form a union, the United Steelworkers union announced Thursday. The union, the collective bargaining agent  for the adjuncts, said that Duquesne administrators now have a legal duty to bargain with them. Last week, the National Labor Relations Board voted to count the ballots  on the adjunct vote. The ballots were impounded following an appeal by Duquesne that the adjuncts should not be allowed to unionize because a union might affect the Roman Catholic university’s religious freedom. The NLRB decided to count the votes saying that if the effort was defeated, there would be no reason to consider the appeal. Now that the votes favor a union, the university’s appeal will go forward.
