Hi we have an electronic clock in system that if your within half an hour of your start time or over it automatically reverts back to your set shift pattern. For example if you as scheduled for the 8am to 8pm shift but you work to 20:29 then it reverts back to 8pm and you only get paid until 8pm. I work in a place we're things happen and can't be passed to the next shift so you have to deal with it. If it goes over the half hour it has to be manually approved by a manager. Is this legal given that you have been there and done the work. It's doesn't put me under NMW. It's more the principle.
