So the office romance per se wasn't the problem but the system that allowed concretely bad things to emanate from it. If the courts take such lawsuits seriously, then that allows people to shift responsibility away from themselves and that's generally when bad things start happening.

In another culture the two would've just broken up, caused a stir in the office, and in the worst case one of them might have left the company if they wouldn't have been able to recover and speak to each other again.
