Depending on your job, it's entirely possible that dating coworkers, colleagues, or supervisors is actually against your company's policy; it might not necessarily be, but it'll be worth researching before you go head over heels for your cubicle neighbor. But although it's tempting to see your workplace as a place to "meet new people," especially because your coworkers are likely the folks you'll see the most, dating at work can be tricky.
Over at QuickBase, Alison Green of Ask A Manager details a few things you may not realize you'll have to consider if you date a coworker; for example, not only will your boss likely worry about how your status as a couple is affecting the overall workplace, but moreover, your SO's problems at work will become your problems, too — even if they shouldn't be. And of course, navigating a breakup is even more difficult when you're seeing each other at work every day.
This isn't to say that dating at work can't be done; however, you'll definitely want to think about it carefully before you do it.
