Negotiations is a subject which has become an integral part of many business English courses.
It is an interesting topic because it is one where the language trainer has to walk a tightrope between providing language training and business skills training. In general I think language trainers should stick to their knitting unless they are properly qualified to move into other areas of training. But with negotiations some knowledge of the subject is important for the trainer because the way a person approaches a negotiation determines the language they decide to use. A good introduction to the whole topic is Negotiating Skills , by Tim Hindle, in the Essential Managers series from Dorling Kindersley. The activity described below is best used after some linguistic input on negotiations has already been done.
