NLP at Work, The Essence of Excellence – Sue Knight, I’ve read this book and referred back to it on several occasions. Whether you are new to NLP or have more experience I cannot recommend this highly enough. It is written in a style that demystifies much of the jargon of NLP and provides a pragmatic approach to applying the key elements of NLP both in your personal life and in the work place.
For those managers working in a business environment the book provides many examples of how to apply NLP in positive way. A great read with practical application.
