I understand that if my shift exceeds 6 hours I am required to take an unpaid meal period of at least thirty (30) minutes. A meal period should be taken in the middle of the work period to the extent it is practicable and requires me to clock out and back in each time. If my work shift exceeds 6 hours I can shorten a one (1) hour meal period to thirty (30) minutes, with authorization from my supervisor, but I can not waive my full meal period in order to leave an hour early
