I have been reflecting on this inequality a lot. I see it in work - men are so sure of themselves, so certain they are right, so confident to go for promotions. Even when they are quite limited in their abilities.
I think this is the crux of it. When I started work I hated my job it wasn't difficult and the women in the office were unpleasant. OH told me if I wasn't happy then I needed to do something about it. He encouraged me to retrain and I started in a more interesting and demanding job. He told me that I had to speak up for myself and push on, take no shit.
It was a bit strange coming from him as he'd just came up if others spoke over him at meetings even if he knew they were talking rubbish.
You can go far in business by being confident and speaking as if your sure. We had a couple of young project managers push forward multi million pound projects that were doomed because they were vanity projects for the board and had little to do with the business. They had the good sense to move on with glowing references before the shit hit the fan. Before I left there was a new project manager, a young lady who was going places, starting the third version of this project. It still wasn't going to work but I had to admire the confidence she had and the way she handled the meetings, she could have convinced you that the C5 was the future of transport.
I understand she has now moved on before they try and implement her solution.
So male or female it's confidence that's the key. You don't have to know what you're doing just inspire confidence. If you do it right then if the wheels come off just make sure someone else is driving.
With a bit of practice you could end up in government.
