Due to a restructure at work I am about to start working with a woman who had an affair with my EX-H for many years while we were married, and his current partner (this is a different person) I am concerned about how they will treat me and how this may make things difficult for me at work. These 2 apparently hate each other and I do not want to get dragged into it. I am very concerned about my ex controlling things behind the scenes with his current partner; he is very manipulative. I would like some advice about what HR can do to protect me and what I should be asking them to put in place. Getting another job is not an option at the moment as I have just in the last 2 weeks returned to work after a long illness. I also do not see why I should have to find another job as I love what I do and this situation is nothing to do with me. I would really appreciate some advice as I do not know where to start and I am dreading it!
