I have an employee at work who is telling others that I am "writing him" up and harrassing him all the time. I have not said BOO to this guy. Now, other employees are approaching me telling me he will not stop. None of this is true, and this employee has done this in the past. I have requested through my boss that this be looked into and must cease. However, other employees have told me that he is hurting my reputation (which as a supervisor has been outstanding) What's up with this yo-yo, and how far can this go?
