Doesn't this kind of policy erode communication within an organisation? How can you expect to develop friendships or improve social cohesion within working groups if people are worried than private conversations can be construed as sexual harassment for being overheard?

I mean if you're sitting for lunch outside the office talking to a friend and someone walks past at the wrong time and catches a snippet of conversation then what?

Howabout if you're having a private conversation on a work phone and unbeknownst to you someone had picked up another recieved and accidently overheard your conversation?

If you have no expectation of privacy at work how will the social dynamic function?
