The strike Wednesday involves members of the University Professional and Technical Employees-Communications Workers of America. Union members perform jobs including running clinical trials, assisting in laboratory tests, managing classroom technology and caring for research animals. Workers represented by the American Federation of State, County and Municipal Employees are joining in a sympathy strike. University of California spokeswoman Claire Doan says the third disruptive strike in less than a year comes at a cost to patients, students and UC communities while doing nothing to help unionized workers get closer to a contract and wage increases. ___ 9:43 p.m. A union representing research and technical workers said it will strike Wednesday at 10 University of California campuses and 5 hospitals in a one-day walkout after contract negotiations failed. Some 10,000 members of University Professional and Technical Employees-Communications Workers of America will take to picket lines statewide, spokesman Dan Russell said. UPTE members perform jobs including running clinical trials, assisting in laboratory tests, managing classroom technology and caring for research animals. The union and the University of California have been at odds since 2017 over issues including pay, healthcare premiums and retirement terms. Members of the American Federation of State, County and Municipal Employees, which represents more than 25,000 patient care technicians and services in the UC system, will join Wednesday’s strike in solidarity. The biggest rally is expected at the University of California, Los Angeles, where presidential candidate Sen. Bernie Sanders is scheduled to march and give a speech. University officials have urged the union to return to the bargaining table. The UC system includes 10 campuses, five medical centers and three national laboratories and has 190,000 faculty and staff and 238,000 students.
