@RayReignAladdin: Depends on the workplace. I knew a boss-subordinate couple that started dating, but kept it on the down-low for a few years. The subordinate finally announced their engagement. As you might expect, it was happiness on the surface but toxic rumors elsewhere. Didn't faze them since they still did their jobs properly and they got married. They straight up said if you don't support it, don't go to the wedding. They're still married, but now they work in different departments (not by political machinations, but because the wife saw an opportunity to advance in a field she wanted and took it).
Point is it's possible but you gotta put up with a LOOOOOOOOOOOOOOT of shit. Easiest way would have been for one of them to quit and work someplace else, I think, but they took the hard road and made it work.
