According to new research from Hay Group, between one-third and one-half of employees report work conditions that prevent them from being as productive as they could be. The book "The Enemy of Engagement" outlines hidden impediments to employee performance such as excessive procedures, lack of resources, and narrow roles. It provides managers with insights and tools to ensure employees are willing and able to contribute at their maximum potential and radically improve productivity. The book is authored by leaders in Hay Group's employee research division and will be published in October 2011.
