Grassy - I think just offering them promotions if they 'twiddle the right knobs, know what I mean, girls?' should be sufficient. You can pretty much play it as it lies from there.
I think Betsmate has - along with some journos - hit the nail on the noggin. This particular incident reeks of a set-up, because you cannot for one moment believe this was the one and only time the man would've made those sort of remarks. There's a huge amount of sexism, now more covert than previously permitted, throughout what were once male-dominated domains, some of which is just fun banter, some of which is more concerned with keeping wimmin out and men in. In this case, while the remarks are sexist, they're blown out of proportion and 'leaked' presumably with malicious intent.
The Wright Stuff discussed this at some length this morning, with the idea of sexism playing either way being raised. But I think it still all goes to context: if it's wilfully used to belittle, degrade, keep someone in an inferior place (cue too many religions), abuse one's status, etc., then it's not a joke. If it's free-and-easy banter between equals, both being amused, it's just meant as fun. But when one side feels uneasy with it and would prefer it not to happen it's overstepping a fine line. Knowing the difference as to where that line is can mean keeping or losing a job.
Much was made of Loose Women constantly haranguing males in the name of entertainment, and asking if this wasn't payback for 'thousands of years of oppression by men'. Believe me, the oppression goes on, mostly sanctioned by assorted religions such as Hinduism, Islam and Christianity, all invoking their deities' wrath if women step out of lines drawn up by mere mortal men.
There's a distinct difference in 'sexism' when a Hindu widow was supposed to throw herself alive onto her husband's cremation and, if she didn't want to expire in such a hideous fashion, would be hurled onto it anyway, or when quixotic sultans could amass young virgins for sexual pleasure, then drown entire harems on a whim. There was a very interesting programme a night ago on Davadasi, the Hindu practice of selling girls who hit puberty into prostitution. It's only practised by the Dalit ("Untouchables"), but the users of such children can be from any caste. Now, that's sexism all right, supposedly not now permitted but still thriving. It's but one ancient tradition, along with all Hindu widows who escape suttee never being allowed to marry again - but they can make ends meet by servicing the sexual appetites of men. Nice, innit? As I say, it all goes to context.
