I am a director that reports directly to the CEO. We have a great relationship and he trusts me to do my job without interference. I recently hired a coordinator for my department who is beyond a go getter but who tends to swim outside her lane. I have given her as many challenging projects as I can to keep her fulfilled and busy but she loves the exposure outside our department and is often volunteering herself for important tasks to other departments. Unfortunately, in a few cases I was the last to know (I know - not good). The CEO has noticed and has told me to try to rein her in - which I am trying to do! Any suggestions or a good book to read on how to catch a tiger by its tail without killing its spirit would be greatly appreciated.
