Pretty much any workplace that isn’t dominated by one gender has a few people that are banging. Every single place I’ve ever worked had it to some degree.

Edit: buncha people wound real tight in the replies. No, I’m not saying this happens on company time.

Exactly, and I get tired of hearing about it. "Did you hear so-and-so is cheating on his wife with so-and-so?" 

No, and it doesn't concern anyone except him, his wife, and the woman he may or may not actually be sleeping with, so why are we talking about it?
