Nope but I wouldn't be against the idea. I would prefer we don't work the same shifts much though. I recall in my last job a work colleague of mine who became a acquaintance started dating another work colleague and it became the talk of the town. Not only that but while he was doing his job he was always distracted by her and visa versa. I could see it being awkward at times when you work the same shifts. Still he has a new job now and they are still together and have a kid so it works for some.
