In this bold new book, business journalist Ryan Tate offers new insight for CEOs and employees alike, revealing how innovation is being fueled by passionate workers and the companies that give them the time to explore what they care about most. Yahoo's Hack Day, Manhattan's Shake Shack, Stemlicht's W Hotel redesign, and Google's 20 per cent Innovation Time Off have all provided employees with a revitalized sense of purpose and autonomy - working on projects of passion not only allows workers to be personally invested in the work that they do and to come up with creative solutions, but it also often leads to revolutionary products and increased profitability. "The 20% Doctrine" shines a light on the thought-leaders who are shaking up the corporate landscape, visionaries whose advice and experiences can offer salvation for corporate America. With its emphasis on risk taking and experimentation, this book is a bold new roadmap for shareholders, CEOs, and every worker who is critical to their company's success.
