What is that one book that you recommend every HR professional to read once in his/her Career?  Well its hard to tell, isn't it? I have given two. Do you agree with me? What are your favorite picks? 

HR Disrupted: It's time for something different, Lucy Adams

The central question this book sets out to answer is: if we are to survive and thrive in this new, volatile business world, how do we lead, manage, engage and support our employees in a radically different way? HR departments, and companies, need to transform their approach. This entails not simply tinkering with the process or the mechanics, but taking a completely fresh look at the entire scenario. It's the difference between spending hours deciding how many grades there should be in an employee grading system, and asking if grading people actually increases their ability to perform better in the first place. To achieve this change, Disruptive HR has three pillars: 1. Treating employees as adults not children 2. Treating employees as consumers or customers (not a one-size-fits-all approach) 3. Treating employees as human beings EACH: Employees as Adults, Consumers and Human beings. (Each of us is different, each of us deserves better.) So what happens when you read this book? First, there's the lightbulb moment: 'I do that and I hadn't even realised it'. Then you'll see what this means for you and your organisation, with practical tools, ideas and techniques so you can start making changes immediately. And finally, the hard bit: this book will help you introduce this new thinking to others in your business.
