Acknowledge good performance

Too many managers look for people doing the wrong thing, this is a terrible way of dealing with and more importantly motivating your staff.

Good leaders look for people doing the right thing and acknowledge it loudly!

I have found this works really well as people want to feel good about themselves and will in fact work harder to get that positive recognition.  A note from the boss saying well done means a lot and guess what? It costs nothing!
Public praise lifts morale across the board.

Be a Leader not a Manager
