Nurses at 3 SoCal hospitals kick off 5-day strike

LOS ANGELES (KABC) -- Registered nurses at three Southern California hospitals kicked off a 5-day strike that will run through Sunday.

Nurses started striking Wednesday at Riverside Community Hospital, West Hills Hospital, and Los Robles Regional Medical Center.

They say they have repeatedly raised concerns about serious under-staffing.

HCA, the corporation that owns the hospitals, called the strike "absolutely unnecessary."
