Looks like you may have a wage and hour case and potentially more. You are entitled to overtime pay and meal and rest breaks if you are a non-exempt employee. You should contact an aggressive and experienced employment lawyer who represents employees immediately.
One other thing I would clarify to the previous answer. A non-exempt employee (in most cases) is entitled to one 10 minute break for every 4 hours of work OR MAJOR FRACTION THEREOF. So if you work 6 1/2 hours you are still entitled to two 10 minute rest breaks. Rest breaks are paid.
