Seriously though, you might wanna consider SECRETLY telling ex co-workers about the alleged affair and keep in contact with them. If and when the affair costs one or both of them their respective jobs, you can then try to be re-hired. Because you told your co-workers, they will be your witnesses regarding wrongful termination. Heck, one of those co-workers might even give you better advice than I am! It's worth a shot, depending on how much you loved that job!
