Re: Ok...ok...
It's a good thing you're not generalising here, isn't it?
From what you've said, the problem is non-productive workers. Get rid of them and replace them with productive ones. However, you may find that the replacement productive ones are, in fact, women. And before you open your mouth to respond, do try to remember the number of useless twats you've worked with who are, in fact, men.
I currently have three women and two men in my team. The least productive is the white guy, the most productive is the black woman. I don't give a flying fuck about what gender/colour/inclination/whatever people are, as long as they can do their fucking jobs. You should try it.
