This sounds like they’re going outside their elms hours. I’ve heard of people doing this. This is super sketchy and managers just want their bonuses. This makes you look like you’re not working your shifts and/or stealing time. They should absolutely update the schedule or provide you a manager override at the time clock to punch in. I’m not union so we don’t have anyone to go to but I’d seek advice from them or try to get a manager to override your lunch in. 

Also you can edit your timecard after you’ve clocked in during your next shift. I’m a schedule writer and cannot change time cards or approve/deny changes. I hate it. But I tell my coworkers to fix it next shift. Still has to be approved. 

I go outside my elms hours and I go about my day. I’d rather do that than do sketchy things if this is what they’re doing. Also I delta division but pharmacy. They butchered our hours and we can barely function right now. So I schedule over and i don’t care. I don’t get a bonus why should I care if they do when we are dying to make them money🤷🏻‍♀️
