The Service Employees International Union under President Andrew Stern, as this publication has noted more than once, is committed to maximizing membership in its own ranks and in the labor movement as a whole. Part of this ongoing campaign involves backing union-friendly political office-seekers. But in Southern California this alliance has produced a downside: bad publicity and a pair of investigations. The focus of attention is SEIU Local 6434, also known as the United Long-Term Care Workers, and its embattled president, Tyrone Freeman. On Thursday, August 21, Bernard Parks, a Democratic candidate for the Los Angeles County Board of Supervisors, demanded that his opponent, Mark Ridley-Thomas, also a Democrat, return more than $4.5 million raised by a union-led alliance whose driving force is Freeman.
