@MrMountstevens Perhaps they aren't planning but are marking or prepping resources? After all, the question only specifies planning rather than school work in general. Or maybe they are just super efficient and put a shift in on a Friday night?
@timjinx@TinaDaheley Isn't that we say 'on Friday' to signify the next Friday coming up even if that's 6 days away and that would be 'next Friday' to you? Next Friday for us would be the one in two weeks time, what you rather old-fasionedly call 'friday week!
