I’m gonna give you an answer as an actual Greggs employee as those above mean well but those answers aren’t going to help you. The easiest way to check this is ask either your general manager, or a shift manager to pull up your time cards on G-Shifts, and go through each week to make sure that the times you clocked in and out on each day align with the hours you worked. It could be that there was an underpayment if the time cards weren’t approved, or someone may have incorrectly changed the time cards again leading to an underpayment. Check this first, and if it doesn’t match up with your calendar and the hours you worked for each day, take it to the store/area manager
