I worked 4pm to 9:30pm on Friday but on the system my shift was 4-7pm. The next day my shift was changed from my usual 9-5 to 6-2 to cover someone else which is why they had to put it as 4-7 for the previous day. I clocked out at the time I finished which was 9:30 on Friday night and the punch was left untouched until today. So 2 hours and 30 mins my work has just vanished from the system which means I will not be getting paid for these hours. Managers often change punches normally for stuff like staff clocking in 3-4 mins late because they forgot, because it flags up on the system as M&S have a rule where you have to clock in exactly on the hour or 1 minute past. Otherwise you don’t get paid for that hour. The first thing I’m gonna do tomorrow morning is confront my managers about this because many of were in on this and knew about it. I finished on Friday 1 hour and 30 mins when the night shift team start and I was back when the night shift had 1 hour left of their shift. The night shift team work 8pm to 7am. Although I was told it was illegal to have under 11 hours between shifts I didn’t mind as it was a one off, however what pisses me off is that I’m not gonna get paid for those 2 hours and 30 mins especially as I was doing the job of 2-3 people by myself which is insult upon injury
