That's it really. I can give more details if needed, but basically I have been the subject of grievances at work that are based on lies by two people (who are friends). They have been about my professional conduct and I feel therefore that my reputation has been damaged no matter what the outcome may be. Several of the accusations are easily provable as lies while others are more dependant on things like tone. I see on Google that there may be a possibility of suing, but what is the likelihood of success?
