You would be shocked how many people lack what one would hope is common sense when it comes, especially, to things like shift scheduling. Even ones who've been on the other side of it and get promoted!

It seems it is not common sense after all. And no, most of it's not happening because of reasonable business trade-offs or tension between business and human needs, people are just weirdly bad at making sensible schedules. They'll produce these completely fucked-up schedules that someone with a little empathy and that aforementioned common-sense can fix in five minutes flat. It's baffling.
