My employers time system runs in 15 minute intervals. So if you are supposed to be at work at 9:30 and get there at 9:38 you are technically getting paid from 9:45 on. They are fine with that of course. However, if after we are closed and everything is done we want to leave at 5:24 they will not let us and arbitrarily make us stay until exactly 5:30. My Boss gets VERY upset when some leaves at 5:24 even though according to their own system they will get paid until 5:30 and there is absolutely nothing to do. We literally stand there holding onto our belongings looking at the clock like a bunch of school kids for the bell to ring so we can go home. I guess employees are going to have to start being like that as well. If they show up late and they want them go ahead and get started “Because we are busy” they should just stand there at look at them until the next 15 minute interval comes up.
