Ok so im a part time worker and I come in every day 15 minutes early to setup the trailers. Well the pt supervisor has been forgetting to add my 15 minutes to my time and it's starting to get on my nerves. Sometimes he'll add it or sometimes he may forget 3 days in a row. What should I do ? And also If the answer is to file a grievance, what happens to the pt supervisor? Does he get in trouble? Thanks in advance.
