In California, generally employers are required to provide employees with a 10-minute paid rest period every four hours of work, and an unpaid meal period of at least half an hour. So, assuming you were working an 8-hour shift, you should have a paid 10-minute break close to the 2-hour mark, and again at the 6-hour mark, with a half-hour unpaid meal period in between. The penalties for an employer failing to provide these meal and rest periods are steep and add up quickly. If other employees are also being prevented from taking meal and rest periods, they may also have separate claims. With regard to the cell phone, I would expect your company to reimburse you some portion of the cost of your monthly service charges for using it for work purposes. I would recommend that you consult with an employment lawyer as soon as possible, primarily regarding the meal and rest period violations.
