Drawing on case studies from leading companies, including Disney, DHL, KPMG, and Pepsi Bottling Group, best-selling authors Gostick and Elton show how the transformative power of purpose-based recognition produces astonishing results. And they show how great managers motivate employees to excel by offering constructive praise and meaningful rewards, and in doing so achieve higher productivity, engagement, retention, and customer satisfaction.
