Thanks some good thoughts. I've been thinking a bit about it too lately. I plan on calling more rather than the easier emails. I am making a conscience effort to make sure I thank people more and to point out exactly what I am thanking them for. I always felt I thank people regularly, but I also realize in an email it may not come across the same.
I am also going to formalize my one on one meetings that I hold - with an agenda and send early so my managers can add items they may want to discuss. In the past, I've been more informal with these meetings and they seemed to work very well this way - but I was face to face with people.
Also, in our performance system, we have a working notes sort of area - I've used it in the past with individuals when we had performance issues. You type in items discussed, etc so you have a formal document as you progress through the year - it is not required, but I figure by putting in the notes after our meetings it should solidify any discussions we had so there would be less confusion and to clarify. The manager would also have access to view so it may be a good tool under these sorts of situations.
