You said 'Hi Emily. This won't take long - I'll come straight to the point. Recently, at work, there's been one or two occasions where you've been a little uncooperative, surly even. Do you know the times that I'm referring to?' Well done! You have gone into this tricky conversation quickly, which makes it easier and less painful for your employee. You have also asked a question, which is the first step to reaching an agreement with her.
Emily responds by saying 'Are you talking about what happened at the meeting?' What do you say now?
