First thing they told us in training sessions after promoting us: you head home at 5:30, and remove pressure for your subordinates to stay in the office.

You may login after hours to wind up your day's work (it is, in fact, expected), but you are to make damned sure nothing hits your subordinates' inboxes until 8:30AM the next day. If that means putting delays on your messages in Outlook, so be it.

Makes for a much more relaxed and productive team.
