1. DON'T get angry.
"Getting angry is easy. Anyone can do that.
But getting angry in the right way in the right amount at the right time, now that is hard." (Mark Twain) Anger does not belong in your managerial kit bag.
2. DON'T be cold, distant, rude or unfriendly.
Especially in difficult times, employees take cues from their immediate supervisors and need to hear from them.
