Taking days off
Assign the things to do to your employees in writing before you go. Not more than once, at about half-time, call your deputy and ask how things are going. Resist the urge to intervene for that would put all responsibilities back to your shoulder. Do not show your emotions about the sleaziness after your return. Collect facts and make the right people face them. It is not always the case that people undermine you during your absence, but you'd better be prepared.
