FILE - In this April 30, 2012, file photo, Yvonne Walker, president of the Service Employees International Union Local 1000, leads a walk for health with Dr. Mehmet Oz, in downtown in Sacramento, Calif. The president of California's largest state employees union has been ousted from the post she held for 13 years and replaced by a candidate who promises to end the organization's political involvement while bolstering its membership, according to results from a low-turnout election posted by the union. Under Walker's leadership since 2008, SEIU Local 1000 was a thorn in the side of the state's last Republican governor, Arnold Schwarzenegger, but grudgingly negotiated other austerity moves with his two Democratic successors.
