What can you do? Hypothetically you take each one of them aside and you force them to tell you what she’s been saying about you. And then somehow demonstrate that she is lying.

Now that’s hypothetically.

Realistically, there’s no way that they will want to change their mind anyway. Unless you have some really solid proof that you didn’t do it. And ans anybody can tell you , trying to prove a negative is almost impossible.

So that means realistically, there is really nothing you can do about it. I mean, you can catch a couple of them when they’re alone. And try to find out what She said. But if they’ve already bought into the bullshit from her then what do you do?. I don’t really see a way back from that.

By the way, I’m going on the basis of she’s lying and that she falsely accused you. As I only have your comment in the other post where you said she falsely accused. I have no way to know what did or did not happen. I’m just giving you information based on what I have. All I can say is good luck and try to move forward. Only you would know if you’d be able to approach those people and have a chance of sitting down and making them listen.
