Yes indeed. Very good idea. Little things like this matter–they’re not little things really. I remember when I was working that a quick email or a phone call from my boss telling me she appreciated the work I was doing meant as much to me as a raise. (But raises were nice too). When folks are doing good things, recognize them!
Coaches, like managers in the private sector, have to offer constructive criticism and feedback. My theory back in the day that I managed people was to be just as quick to praise when deserved as I was to criticize when that was deserved. That principle served me well. I suspect that if these coaches keep running the show the way they’ve started, that when the day comes that they have to rip one of the guys a new anal opening, that it will be received as being constructive rather than destructive.
