What Makes A Negotiation “Fair”?

When we enter into a negotiation, it is our goal to use our negotiation styles and negotiating techniques reach an agreement with the other side. Although we may never say it, we expect that agreement to be fair for both sides: nobody is going to be taking advantage of anyone else. However, as the negotiation moves along, we may start to have some doubts. We may start to wonder if the other side is treating us fairly. In fact, we may wonder if this is really a fair negotiation.
