Power exists in every relationship — whether we like that idea or not — and to be effective in any role, power needs to be understood. In this episode, Matt Abrahams sits down with Professor of Organizational Behavior Deborah Gruenfeld to discuss her new book, Acting with Power: Why We Are More Powerful Than We Believe. Deborah shares how body language can give us power, or take it from us, and advises how we can use power for good.
