Where does it say that a 15-minute break in the morning and afternoon is required?
There is nothing in law or regulation that entitles an employee to a break during the work day. Supervisors may, but they are not required to, grant employees a 15-minute break during a 4-hour tour of duty, or two 15-minute breaks during an 8-hour tour of duty. This is not an employee right, but a discretionary option for management. Employees may not use a break or rest period to shorten the number of hours in a workday or extend a meal period.
