Oh stop spewing bs about sexual harassment as "hitting on" people. The accusations against the VCs McClure and Pollock involved groping or worse.
I've witnessed this:
(concerned) Is x OK?
Huh?
Is she upset? She looks like she's been crying.
(realising) No, she's just not wearing any makeup. You normally see her with makeup on.but you can talk to men how you want, they won't care.
so yes you have to behave differently to both genders.
However, the reasoning for that is interesting - the primary reasons women get more upset when you speak about their appearance negatively when compared to men is that women constantly have it drilled into them that their appearance is one of the most important things about them, from a relatively early age. We have a combination of media and other people who do that - often even other women.
It's something to be solved, but as the situation stands right now, yeah, criticising women on their dress/makeup/haircut only serves to further that - because women have generally already had significantly different experiences than men by the time you meet them.
Or, in other words, if you think makeup is intended to replicate visual signs of arousal... then this is the culture you work in forcing women to appear sexually aroused in workplace environments. Which is, of course, also something that feminists have talked about for decades.
I recall reading that if a woman has no other female coworkers, the trend is a decrease use of such signals. With no one to compete with then there is no need to spend energy on it.
Like how "men" are claimed to be responsible for pressuring women into unrealistic body images, despite the fashion industry being run, and chosen by women.
Various celebs will back a "ban bossy" campaign, but millions of women are forced to feign sexual availability against their wishes, and barely any motivation to protests it?
Fact of the matter is, if you employ women who don't wear makeup, your clients and customers will think less of your business. You'll lose money and some positivity associated with your brand. Your managers will think less of your female workers - so will their coworkers, no matter the official policy. This isn't the sort of thing that gets changed by a line in a policy document - this is the sort of thing that needs widespread social change.
On that basis, the idea "women are socially pressured into wearing make-up" falls short. Women, themselves, are rejecting the idea.
> your clients and customers will think less of your business
This isn't all jobs, though.
A doctor, or back-end dev shouldn't feel any pressure to wear lipstick.
If you want to direct criticism at those roles/instances where there is a problem, and maybe suggest solutions, I'm fine with that, but broad strokes don't do much help.
Incidentally, I see fewer women in my own country wear as much make-up as those in America appears to do. I mentioned "doctor" specifically because I am surprised how much american doctor wear. As a further anecdote, whenever an american version of a European series is remade, the american actors are usually more attractive..
