Peter Randall's book, Adult Bullying - Perpetrators and Victims, is a "must read" for everyone. As a person who has been the victim of bullies, both in the work place and personally, I found the book very beneficial in understanding why some people become victims and other bullies. The case histories were interesting, as were the proposed interventions.
As good as the book was, there were a few problems. Randall makes the point of the bully's responsibility and that the victim needs to understand how he or she is contributing to the situation. However, I think he could have done more with discussing the responsibility of others, both those who join in with the bully and those who simply try to ignore what is going on. For example, he points out that others may feel that the victim deserves the bullying because the victim is not strong enough to stop the bully. However, from personal experience, I know that for some people it is more that they do not want the bully going after them. Also, while many of the case studies and descriptions of interventions are transferable to America, there are clearly some cultural differences that were a little distracting. A little explanation in those instances would have been helpful.
Overall, this is definitely a "must-read" book, whether you have been a victim, a bully, or a by-stander.
