Unless you have a written contract or are a member of a union, California is an "at will" employment state and you can be fired for no reason or any reason (so long as it is not for belonging to a protected class, e.g. race religion, etc.) If you can be fired, you can also have your salary reduced, but not to less than minimum wage.
