It sounds like you are defending the exact office culture that makes women in particular feel very uncomfortable.
Were men putting their hands on the shoulders of other men for instance? What is "tactile contact"?
women feel uncomfortable when someone puts their hand on their shoulder, hugs them or shakes their hand? Only the hyper sensitive snow flakes that seem to be everywhere these days, but certainly not the women I've known growing up and not the women I worked with - at least not until now and low and behold it's the 25's and under which are whaling away at every opportunity they get with claims of sexual harassment or discrimination. We have a 24 year old girl in our team who's gone complaining to HR of sexual harassment because one of the Directors in the team asked her to take a new photo with a grey background instead of the blue one she has in hers currently. No joke. The same was asked for 2 others who have their photos with a blue background and not the standard grey one that is now company standard - not that she stopped to ask as she went straight to HR to complain after the request was made. Needless to say the decision has been taken to sack her over the coming 6 months as we simply have no more patience for individuals like this.
Norms change. I think people are less likely to put up with things they don't like...
Also, I started working about a decade ago as well, it's never been the norm in any place I've worked. Perhaps I've been working with robots without knowing it.
I started my career in investment banking which is the stereotypical setting for apparently predatory behaviour but I can honestly say we never ever had an issue. In fact we had an amazing team which included 1 male Managing Director, 2 male directors, 2 female directors, 4 female VP's, 2 female associates and 4 male analysts including me. Putting your hand on a person's shoulder, leaning over their desk discussing thing or even hugs in the morning/evening were entirely normal - the female VP's even used to invite us lower ranking fella's to their places for movies on the weekend etc and we are all still friends to this day and till meet up regularly. We didn't start as 'friends', we started as colleagues but building genuine rapport was the product of that human tactile connection.
Actually, we were having a discussion about this last week and even the girls thought this notion of hand on shoulders, or touching as sexual harassment was absurd. It simply wasn't an issue back then and I can't see why it would or should be an issue now. Actual sexual harassment is abhorrent, but touching someone's shoulder in the normal course of your interactions with them? get real
