How to deal with a disrespectful employee

Q. One of our employees constantly twists everything I say around to make the situation seem worse than it is. For example, when I put her paycheck on the counter because she was doing something, she told others that I threw it at her. She has lied about many incidents. I have spoken with her several times and indicated that her actions are unprofessional and disrespectful. This is not good for my reputation. I need a solution. —S.W., Texas
