Some 13,000 California nurses threaten to strike

Nearly 13,000 nurses at hospitals across California intend to strike next month if their staffing concerns aren't addressed at the contract bargaining table.

National Nurses United bargaining director Jill Furillo says the one-day strike on June 10 involves nurses from all University of California hospitals, Citrus Valley Medical Center in Covina, San Pedro Hospital and Olympia Medical Center in Los Angeles.

The union says there isn't enough staff to treat patients, requiring more attention from nurses.

California law mandates hospitals to maintain specific staffing levels in different areas of the hospital. For example one nurse must be present for every two critically ill patients.

Calls to the UC weren't immediately returned.
