If your boss violates California rest and meal and state laws, you may be able to sue your employer for not allowing you to have your legal amount of meal or rest breaks. For instance, if your employer denies you a meal break, or does not compensate you for your rest break, they can suffer real consequences.
Under California law, an employee must be given breaks every five hours. You cannot work for more than five hours a day without be given a meal period of at least thirty minutes. If your total work day is only 6 hours in that case a meal break can be waived by both parties.
When you work for more than ten hours, a 2nd meal period of not less than 30 minutes must be allowed. Again, if you are only working a total of 10 hours or less, the 2nd meal period can be waived by mutual consent, as long as you did not waive your first meal break.
