I have two employees who dated for a year. It has been a year since they broke up but they are trying to remain friends. They don't work in the same work group or on the same projects, but we do have a small office (35 people) where the young and single people spend a lot of time going out together. For some reason, when they get together and alcohol is involved, it always turns sour. I have had him block her on his company phone, and her complain that he doesn't respect her. we have dealt with any disrespectful or unacceptable behaviour at work but they are both saying that the other is causing them stress and that it is affecting their work. I have finally asked them to block each other on their phones to limit the text messaging after hours which gets out of hand. How much more can I really do if they insist on fraternizing after hours? Both are really great hard working employees.
