I don't think we should be talking about ironing boards (mine is amazing, by the way), but broader industries like finance.
Trading, for instance, has been mentioned as a field particularly well suited to women. First of all, we're BETTER at it - see here and I WISH I could find the article I read a couple of weeks ago, poss. in the Sunday Times about how fund management is a very scalable job so very suitable to flexitime or part time work. It's not tied to different time zones or markets and you just manage the number of funds appropriate to your hours, so you can work 3 or 4 days a week very easy, and still make masses of money.
But when has trading or fund management EVER been represented as a woman friendly industry? They are the very financial areas we probably think of as being the most male-dominated!
It's not about board quotas, it's about encouraging our 6 year old girls to be competitive, to run faster, to think of maths as innately suited to their interests and through secondary school to quietly present finance, investments, money and so on as representing specifically female interests - after all, if they're going to be the ones to spend 70% of it in the end, they should be managing its growth it in the first place!
If 50% of all trainee fund managers are young women with degrees in economics then it follows that 50% of board members will eventually be women, especially if it is a career that doesn't have to stall when you have children and choose to come back with a flexible workload. Hopefully by that stage, our daughters' husbands will also see the virtues of an 80% week and
It's not fair (and I say this as a feminist with extremely strong beliefs) to chastise companies in these industries for not having full female representation at board level, when our daughters aren't applying for their entry level jobs in the first place.
(I'm thinking specifically of the financial industry in this post, obv.)
