Working Laws in the State of Ca

To whom is reading this,
Today is the day I have to stand up for my rights... If you have asked why everything happens to me the real answer is unknown. I have though about it and I have an idea, I am a double minority. I am a female and mexican. Well, what happens is that since the age of 15 I been working for a person/store where my salary is horrible, everyone has bad working conditions, I never get paid for overtime and our lunch and breaks have been never respected. We also get paid under the table to prevent our boss to pay more taxes. Many of my coworkers get pay less  than what the minimum wage is in the State of California. The answer from my boss from all these violation to our rights is that many of them do not have the legal right to work in the United States. However, that should not be an excuse because the law says that it does not matter the employees legal status, these people still have the right to get paid at least the minimum wage and get full and on time lunch and breaks. I have talk to my boss because I know that what he is doing is not the legal thing to do, his answer to everything is that he doesn't want to make things complicated for him and that he does not make enough money to pay everyone  minimum wage and that is too complicated for him to arrange everyone lunch schedule.  Still he has seven working people working for him, these people know what their right are and do not do anything. Reason: Unknown. Although I think they are scared of losing their jobs. I did not say anything before because I did not know my rights and later because I needed this job to support myself I was scared of losing it.
Now, I made my point clear to my boss a least I need 30 min of break when I have to work ten hrs a day (what a hell I am thinking right!) Today, he has to talk to me because my coworkers complained about  my ability to get a 30 min break out side the store when they can not do that. I thought to myself  I have to stand up for my rights and if others do not want to do that I should not let this step over me...
See you later, I have to get ready to go to work!
