A concerted effort by an international union to link up adjunct US faculty members is succeeding in its city-by-city approach. The Service Employees International Union has enlisted about 70% of adjunct faculty members in the Washington DC area. Malini Cadambi, the union's higher-education campaign director, says that 80% sign-up is possible. The union last year launched similar strategies in Washington state and Massachusetts, and is expanding to seven more US regions. A wide membership base provides adjunct faculty members with more bargaining power in their push to raise pay, make evaluations fairer and boost academic freedom, says Cadambi.
