COOPERATE WITH the administration 100 per cent even though you disagree with it 100 per cent. If in disagreement, have a friendly chat to attempt to reconcile differences. This conversation should be with the administrative officer and not with colleagues or students or outsiders. If there is discussion with colleagues it should be in a staff meeting in which discussion is invited.
Respect your colleagues, giving them the benefit of every doubt until they demonstrate that they no longer merit one's respect. It is a great temptation for an authority in one field to recognize little or no merit in a colleague in another. One's own eminence is never enhanced by attempting to tear down another's.
Be loyal to one's colleagues as well as to the administration. Institutional harmony is based upon mutual loyalty and respect.
Never repeat gossip to a living soul. Await verification.
