Mika also gets honest answers from the likes of Donny Deutsch, Jack Welch, Donald Trump, and others about why women are paid less, and what pitfalls women face €" and play into.

Knowing Your Value blends personal stories with the latest research on why many women don't negotiate their compensation, why negotiating aggressively usually backfires, the real reasons why the gender wage gap persists, and what can be done about it.

Written in Mika's brutally honest, funny, and self-deprecating style, Knowing Your Value is a vital book for professional women of all ages.
