Litigation in California over non-payment of overtime to IT workers

Is anyone aware of any resolved or pending litigation in California against Kaiser Permanente over its treatment of its IT workers as exempt from overtime payment? It is my understanding that this situation of potential mis-catergorization of IT workers at Kaiser existed at least up until recently when they may have outsourced all of their IT to contract labor. Any information, thoughts, or comments would be of interest to me for my research in this area of labor law.
