Men wouldnt get felt up by their fathers friends as 'a joke' when 13yo.
Men wouldnt get routinely sexually harrassed at work and, at the time, see it as a normal 'rite of passage' so as to be taken under the males wing and taught everything in the job to get ahead.
Men wouldn't get told by their boss, and good friend, not to wear their hair down to a business meeting because 'its too sexy, and distracting'.
Men wouldnt be ignored by clients around a boardroom table, instead deferring to their more junior male colleagues. What a surprise the clients got when it came time to negotiate and said junior colleagues turned to me to say 'she's the boss'.
Men wouldn't get told whilst sitting with industry colleagues after an event (all of us director level and above and above) that 'you're brilliant but we'd never hire you at your age now 'cos you're just going to go off and have babies soon. Ha ha'
Men wouldnt be fired from their VP job within 2 days of announcing their pregancy with no performance issues, ever, quite the opposite in fact.
I could go on and on sadly. Haven't even touched on the daily life 'niggles'.
