Picket lines formed across California Wednesday as 20,000 health care, research, and technical workers in UPTE (Communications Workers Local 9119) and 37,000 patient care workers in AFSCME Local 3299 walked out on short strikes across the University of California system. AFSCME will stay out for two days, UPTE for three. Both unions are charging that the university system is engaged in unfair labor practices. They have been working under an expired contract since October. The workers struck in November, too.
