You can't prevent people from having relationships. It's not realistic. My company has specific rules about this. Typically, "problematic" relationships need to be disclosed to HR and leadership, but they're not forbidden per se.

They may not think about it that way, but if one of that couple got a promotion from the other then every other person on the team pretty much has grounds for a law suit. There are reasons these rules exist, and the CEO of a high profile company has no excuse not to know them all.

She was a direct report of the CEO. There are no promotions possible. She was max level already.

But was she a direct report when the affair started?

Extremely rare (winning such a lawsuit). Prior to these kinds of rules becoming the norm, how often did anyone win such a lawsuit? It's a rounding error close to 0.

There are plenty of publicized cases where one party openly stated she got promotions because of her affair with a senior. No lawsuits were even filed in the ones I know.

I'm in favor of such rules precisely because it's hard to win such a suit.
