No, I use this option as very last. I have to admit I have a hard time to let somebody know that he or she is not doing their job. The atmosphere at our work place is quite friendly and we treat each other equally.
I usually try to hint to the person that there is a room for improvement in certain areas. I use positive approach all the time.
But when everything fails I go and talk to management. Again, I try not to be negative and ask them to approach the person in a sensible way.
