Eh. It can kind of cause a lot of problems in the workplace, and not just for the people dating… Especially if somebody is the type to get jealous if you have to work with their partner on something, which is sadly not uncommon. If you’re mature and can deal with it… fine. But, frankly, there’s plenty of fish in the sea and it’s probably better to date outside of work (or at least your team) for everybody.
I’ve seen work relationships go very badly but I’ve also seen them go very well. I met my wife at work so it worked out great for me.
Best advice I can give is, if you want to date people you work with, make sure you’re ok with quitting your job. If things go south it might come to that. Use good judgement. Don’t date your boss or one of your subbordinates. That’s a great way to get fired out of a canon.
My brother-in-law dated a co-worker for a few weeks a couple of years ago but he went over-the-top like with most things in his life, so things went south fast and now it’s been difficult between them at work ever since. He is definitely not okay with quitting his job, and apparently neither is she, so now they’re stuck with each other, so I would say it’s a very tricky needle to thread.
