Yea it's tough. As a manager I dealt with this recently. Had a guy who was an absolute star. Technically very sound. Committed to doing things properly. Managed his time diligently and productively. Tried to help everybody. Reacted badly to every attempt I made to find somebody to assist him. I wanted to make sure he could take a vacation and not get a phone call. Also wanted to make sure the company had somebody in place who knew the work in case he decided to leave for some reason.
