Conundrum

Subtitled: HR Nightmare
I told you a few weeks ago that I was with a new company that embraced the social media platform. Share, like, emoji, means more activity for your location. More activity equals more views equals more, more, more. Sound theory on paper, in a digital world.
Tonight I was scrolling through my Facebook alerts and came to "people I should know". Most of mine have links to wineries in the area or growers of a particular grape that I enjoy ;)
Tonight, however, a current employee came into the feed. 4 mutual friends. 4.
Deep breath, a cigarette and an a little bit of an overpour of wine before I continue.
Still here? This post will require some comments, hopefully a full discussion with some back and forth. I'm ready...
Hypothetically we have Joe. Joe is a hugger. He hugs everyone. Then one day, for some unexplained reason, he didn't hug someone that he was working with. And just the one person. Discrimination, of one, harassment of all others? I don't know but it's not about Joe. It's about me and 4 mutual friends.
I said this is a new frontier a few weeks back but today I found myself in a conundrum. If i embrace the social media aspect and go for likes, shares, etc., then have I put myself in an HR nightmare? I can send a request that the employee may feel forced to accept which is wrong or not send the request which is the equivalent to Joe not hugging. Still wrong.
Will the future of business be decided by how we snub or accept co-workers on social media?
