Stacey Vanek Smith has reported on business and the economy for over 15 years now, first for public radio’s “Marketplace,” and as the host of Planet Money’s daily podcast “The Indicator.” Over that time, she’s seen the same barriers blocking advancement for women in the workplace again and again. Recently, she’s started to recognize that a lot of tools to move past those barriers can be found in the work of Italian philosopher Niccolò Machiavelli. Vanek Smith lays out these solutions in her book, Machiavelli for Women: Defend Your Worth, Grow Your Ambition, and Win the Workplace.
