A colleague has put in a grievance against me. She has also resigned/ walked out but wants to retract this. Part of her grievance is justified. I joined in some gossip about her as she was having a pretty public affair with a close colleague of mine. I shouldn't have done this and have apologised. But she's also accused me of a lot of stuff which isn't true at all. I don't know why she's done this. Can anyone advise what will happen? It's my word against hers. We don't have HR at work so I am really anxious about what will happen to me.
