Query: It is singularly the most powerful book on violence at work!

In my work I have read about and worked on several projects dealing with the topic of Workplace Violence. This book by Lynne McClure is clearly the best book available on the topic. Lynne is both insightful and available, she offers strong content on the organizational side of the workplace violence issue as well as the employee side of the issue - it is simply the most balanced look at the escalating issue of workplace violence available in the market today. I feel that the book provided a strong benefit to my work and outlook on the topic and the video based on the book (available through Excellence in Training Corporation), served as an equally strong tool for setting workplace violence policy issues within my organization. This is a "must buy" for anyone responsible for monitoring or setting policy on the liability limitation issues surrounding workplace violence.
