When you coach your employees, do you unintentionally declare war with your choice of words? Managers who use emotionally charged words in their feedback to employees undercut performance improvement. It’s not what the manager says but how he says it that creates the problem.
Instead of telling your problem employee that he is unproductive and that he has a bad attitude describe his performance in less subjective terms. Does he miss deadlines? Does he raise his tone of voice with customers? To get the best results from your employee, be calm and specific and choose your words carefully.
