Legal Advice about tips?

I work for a corporate restaurant that I think is doing illegal things. They used to make the servers tip out the kitchen staff, but by California law you can't tip out staff that doesn't have a certain percentage of time with the guests and the kitchen staff has 0% of time with guests. The servers no longer tip out the kitchen, but they did for years. The servers also used to tip out other back of the house staff, but since the law about the kitchen staff also applies to the back of the house staff too, they no longer tip out the other back of the house staff. Now, the servers fill out a time in and time out sheet and initial it. This means that if the staff member came in at 3:58, but was scheduled at 4:00, the managers will change the clock in time to 4:00. This all seems shady to me. How could the staff go about getting back the money that they used to illegally have to tip out to the kitchen and back of the house staff? And who do I contact about notifying the proper authorities about how things are being run at this establishment?Legal Advice about tips?
