And, finally, of course, the inequity of pay between men and women, which can be definitively quantified.
Women have fought these battles by addressing the tone of the workplace, and they have largely won - at least legally. It's not "PC gone mad", but the response of a group that can now, finally, use its own voice to maximum effect. And, men do not suffer from a more civil workplace. Recent studies reported in the Guardian from Cornell University suggest the more PC a workplace is, the more creative it is. And there's not yet been a mass movement of males cowering in fear about each utterance, terrified a "feminazi" will come and tie their testicles into knots if the wrong words slip out. That I've heard about.

Still, surely there are a few rules of thumb suggested by good old common sense. First, never say something to a woman in the workplace that you would not say to a straight man (if you were also a straight man, if you get what I mean) - so "Andrew, that bulge in your pants is very fetching today" or "Trevor, sweetie, get me a coffee with milk and two sugars please darling?" are probably non-starters. "Mike, I really like the cut of that suit" , or a simple "well done" instead of a lingering bear hug, are likely fine.
Generally keeping a bit of a distance from underlings, especially in a social setting, is probably also a good idea, although sadly not followed by many a Kiwi boss who likes to get munted with staff of a Friday night. It happens too much, with often disastrous results.
Is Roger Sutton's experience a wakeup call? Yes, in the sense that it is an example (to the outside at least) where a man in power who was thought to do wrong apologised and stepped down offering no excuses.
We may see too many examples of sexist language in the workplace still, but we certainly never seem to see the buck stop anywhere, so from that perspective, it is a bit like a pleasant, but not in any way unseemly, slap upside the head.
