Registered nurses from Kaiser Permanente and other advocates showed up at a meeting of the First 5 California commission meeting in Sacramento Thursday to protest appointment of their boss to the group. Kaiser CEO George Halvorson was appointed to the commission by Gov. Jerry Brown in May. At the helm at Kaiser since 2002, he plans to retire at the end of the year. The protesters are members of the California Nurses Association/National Nurses United. They showed up at the commission meeting to draw attention to Kaiser’s decision to close a pediatrics unit in Hayward and move patients to a new medical center in Oakland.
