The 'Challengers Pocketbook' is a collection of 24 portraits of 'difficult' participants encountered on training courses and at meetings. Meet the Trapper, the Griper, the Silent Cynic, the Whisperer and their many friends. Learn how to cope with them using such techniques as 'blockbusting', 'psychological judo', 'reframing', 'self-revelation' and confrontation'. Cartoons of the characters add to the humourous approach and there are four mini case studies.
