Hundreds of Kaiser Permanente nurses hit the picket line on Tuesday to kick off a seven-day strike, calling for a deal that includes increased pay and staffing. Registered nurses at Kaiser's flagship Los Angeles Medical Center started picketing at 7 a.m. Nurses said there will be at least 100 people at the picket line at any given time between 7 a.m. and 7 p.m. every day for the next week. The walkout involves approximately 1,200 registered nurses who are pushing for their first contract after becoming members of the California Nurses Association back in July 2015.
