Unionized health care workers at the California Pacific Medical Center have voted overwhelmingly to authorize a one-day strike, according to the National Union of Healthcare Workers.

The one-day strike, which was approved last week over alleged unfair labor practices, would include the 742 union members who work at the Sutter Health-owned facility across from Duboce Park.

The hospital and its caregivers have been in negotiations since January.

According to the union, hospital officials have proposed eliminating 28 beds, which could impact jobs, as well as doubling the out-of-pocket costs that workers pay for health care.

“There is no justification for the cuts that CPMC is demanding,” CPMC housekeeper Catalino Calonsag said. “It was just a year and a half ago that they agreed to maintain health insurance at its prior cost.”

In 2010, Sutter Health committed to keeping CPMC's 100 beds.

Half of the staff that would be impacted live in San Francisco.
