My question involves labor and employment law for the state of: CA

My girlfriend and I were recently fired and not given a reason why. We worked for a private correctional facility for over five years. We were both in higher positions and have done nothing wrong. I have spoken a higher person in the company and he stated that he doesn't know anything and that it was the state that had us fired. I spoke to the state and he said it was the company that provided them with the information and that the company chose to terminate us. The company is not giving us any answers and we still don't know why we were terminated. We are both in the law enforcement field and from what i hear (rumors)we are being accused of dealing drugs in the facility. This will affect both of us for future employment. There is alot more that needs to be said but this is the just of it. Do I have a case?
