It all depends. I don't think that you should narrow the field of people you date arbitrarily. I have many friends who met in the workplace and are currently happily married. Now of course, some relationships might go bad, thus creating a tense atmosphere at work. That situation only happens though if you let it. I don't mind dating women from work, and I've never had a bad experience doing so, but it's also understandable why some don't do it.
