Tens of thousands of health care workers are scheduled to go on strike Monday across the University of California system, including UCSF Medical Center, which rescheduled surgeries and delayed cancer treatments for several hundred patients.

While UC’s six medical centers will be affected the most, every part of the 10-campus system will feel the impact, with workers at student health centers and in some other parts of the campuses also walking out.

The planned three-day walkout is an effort by the American Federation of State, County and Municipal Employees Local 3299 to persuade the university system to increase salaries and address racial and gender pay inequalities.

“It is a major disruption,” said Sheila Antrum, senior vice president and chief operating officer for UCSF Health, on Parnassus Avenue. “We have patients who have been counting on getting their procedures done, people who are counting on infusions who are being delayed.”
