The women at my company make 80 cents on the dollar compared to the men. Also, I pay my employees whatever they ask for.

Yes, but don't sell it like a raise, as men could complain they are not getting one too. It happened to us. Explain them you are adjusting salaries to be fairer.

I know many women that would rather be paid less than be told they're wrong.

How is that not sexist? Who are you to second guess a woman that states what she would like? Do you think you know better because you're a man?

Yes, this is a little sarcastic, but there is a serious question there. Would you ever pay more for a product than the company selling it asks for? I doubt it.

Also, this will allow you to raise her salary by 25% over the next year(s) and you'll end up paying her the same you a man would have asked for....

I think you may be misreading the "Also." The second sentence was likely the point of the post.

Not at all (OP here). I run a successful consulting business, and with plenty of money moving around, I have the privilege of paying my employees whatever they want (adjustments included, usually yearly but also at the employee's discretion). Two surprising trends have emerged over the years:

1.) No one has asked for something unreasonable (i.e. outside of a reasonable market pay range).

2.) The women have consistently asked for ~%80 of the mens' salary ranges.

It came up because of "National Fair Pay Day" or somesuch, I forget what it's called. I thought it was worthy of note that even when given whatever they want, women still don't come out on top. I suppose someone will blame me for this, though.
