Nobody ever said that this negotiating thing was going to be easy to do.  

This can be especially true when you are involved in a negotiation that  has to do with territory, control, rights, or power. Turf battles can arise over any type of scarce or sacred resource in a negotiation.  Often in such battles, two or more groups view the other side as the  enemy and its own side as above reproach. When anticipating a group  negotiation, negotiators tend to view the other group as inferior to our  group on many dimensions, including intelligence, competence, and  trustworthiness. In addition, groups in conflict tend to see the other’s  positions as more extreme than they actually are. 

Just exactly how  should we handle situations like this?
