Under California law (which is much more generous to employees than federal law), if you are a non-exempt worker, you are entitled to meal and rest breaks: a 30-minute meal break if you work more than 5 hours in a workday, and 10 minutes breaks for every 4 hours you work. There are other requirements though. If your boss doesn’t comply with break requirements, they are required to pay you one extra hour of regular pay for each day on which a break violation occurred.
