I left a toxic place a few months ago due to a difficult boss who was retaliatory and pretty much had it in for me. She turned the head of our section against me and when I left, saying farewell via Zoom of course, he did not wish me well. She basically told him so bad lies about me, i.e. made up that I disappear for days. When I resigned, he just nodded. I was a very good worker who had a great rapport with him from the get-go, but she was a Queen Bee and tarnished my rep with him. Well, she's apparently moving on to a new job and he's still there. There's a good chance I'm going to run into him at conferences and that we may need to get along for the sake of future partnerships. So, how do we work this out for the sake of business? I'm willing to let things go if he's willing to be civil and at least say it's too bad things went sour, can we start fresh? I think he knows deep down that she was an awful boss and that he allowed her to toss me under the bus.
