+1. I know a couple who was working in a multi national. She was reporting to him. When they started dating she moved to a different department. Eventually they married, she left the multi national altogether and became a stay at home mom.

I know another case when a lady working in a multi national cheated on her husband with her boss. Soon enough her boss had to “tackle a few challenges “ … in a different country LOL. The bosscame back to the Borg a few years later.

They didn’t say every time, they said all the time - which is true. But as you said, it can work out if it’s disclosed and a person can move outside of the org chart of the other.

No, it doesn't happen all the time. It mostly doesn't happen, and people are aware. You see when it happens, you don't see when it doesn't happen.
