If they charged you for a lunch break that you did not get paid for, then this is a violation of the labor law and you can file a complaint with the state department of labor
and the U.S. Department of Labor. There are no federal laws mandating that an employer give an employee
a lunch break or coffee breaks and Arizona does not have any such laws. As long as the employer pays you for the hours you are working and is not deducting time for lunch, they have not committed any violation.
