Bosses don't mind staff leaving early?
At a few places I've worked at, the boss would bite the head off anyone who arrived late, even if just by a couple of minutes. However, those same bosses wouldn't say anything to staff who left early, leaving work incomplete. What could be the reason for that? Why is arriving a couple of minutes late considered severe wrongdoing, but going home the best part of an hour early, without completing that day's work, is turned a blind eye to? If I were a manager, I'd have a much bigger problem with my staff doing the latter thing.
