Larry Barton delivers a major contribution to the literature with unrivalled wisdom. He is, without doubt, the leading authority on workplace violence. This book should be required reading on the topic for both practicing managers and academics alike.” —Denis Fischbacher-Smith, Research Professor in Risk and Resilience, University of Glasgow, UK

Having known and worked with Larry for many years, I can attest that this book is distinguished for being both compelling and practical—important for anyone who must make difficult decisions in the midst of a pending threat.” —Mark Sullivan, Director (Retired), United States Secret Service

“Across the globe, in meetings, conferences and briefings regarding threats of radicalization, terror, lone wolf attacks and others, the one name that consistently emerges is that of Dr. Larry Barton.

“Customers, employees, contractors, former employees: all are important to your success, and each of them are wonderful until that one day when something, or someone, shares a signal. That is an opportunity to respond sensitively and practice sound risk management efforts to keep everyone safe. In this, Larry Barton’s fifth book, he shares the insights and tools that validate why he’s on speed dial to so many employers.” —Keith White, Executive Vice President, GAP INC.

“The Violent Person at Work represents one of the few business books to address how those of us working in health care face issues you may never consider—it is in the emergency department and medical offices that we often see your employees and our own at risk to harm themselves and others. Larry Barton’s breadth of experience across many disciplines is extraordinary. Be ready for insight that’s hard to find elsewhere.” —Deborah German, MD, Dean, College of Medicine, University of Central Florida, USA
