United Auto Workers, the labor union negotiating for striking workers at the University of California's 10 campuses, claims it is fighting for a UC that works for its students and its workers.But some of its demands certainly won't work for students, and could hurt the very workers UAW represents.UC officials have held more than 50 bargaining sessions with the UAW, and last week reached tentative agreements with two of the smaller bargaining units, the postdoctoral scholars and academic researchers.
