When you reject, belittle, or forget to follow up to an initiative taken by a member of your team, what happens is next time they will think twice before taking initiative.
It is that simple. And the effect compounds for additional rejecting, belittling and forgetting.
This is not to say you have to accept and follow through with every idea. You just need to communicate clearly what is important and what is not, what is “right now” and what is “maybe tomorrow”, what makes the picture and what makes the frame. This transparency is needed for people to appreciate why some things happen and other do not.
Unfortunately most hide behind busyness, that is often just an expression of ignorance (having no idea) or arrogance (thinking everyone has a clear idea).
It is a killer for motivation.
