I agree wholeheartedly with this article - though in many ways it's just the tip of the iceberg.

On communication, not only is it important that you provide information honestly and often, but that you make sure it's relevant. Quite often seniormanagers "cascade" staff with a veritable monsoon of information, but much of it is not what they want to know. Rather, managers should ask staff what they want, and then make sure they provide the answers. This also goes a long way towards raising the credibility of the manager and casting them in a supportive light.
