Effectively negotiating away the Gender Pay Gap.

Many studies have shown that women don't tend to negotiate staring salaries, raises and promotions as much or as well as men do, and that this gap produces cumulative salary differences that can cost women well into six figures after just a few decades of work. One woman's seminars training women to negotiate effectively are now reaching thousands, with positive results. Her advice?

"Women learn never to name a salary figure first, and to provide a range, not a number, if they’re pressed about it. They are coached not to offer up a figure from their last job, unless explicitly asked. The use of terms like “initial offer” — it’s not final! — is pounded into them. And, perhaps most important, they learn never, ever, to say yes to an offer immediately." To avoid the unique risks that women face of being branded as pushy or aggressive, she counsels them to smile, and to be warm and friendly while being firm.
