I honestly do not know how you misconstrued this. And I'm a very objective person.
If that's the company's policy, that's the policy. That's not the policy everywhere else. Again, people meeting and starting to date at work is not uncommon in the world.Pretty sure the company's gonna have some pretty clear "no fraternization" policies that their actions clearly violate, then. So yeah; not the lady's fault, there. In any way whatsoever.
Not always. If the person feels like someone crossed the line, a good HR will look into it and say "yes you did" or "no, they did nothing wrong".If they don't have such a policy, then it wouldn't have ever gone to HR. Unless it went beyond that. Which is sorta the point I'm making.
