Ah, ethics. 

We all know about them, we all know that no matter what  negotiation styles or negotiating techniques we are using, we should be  ethical when we are negotiating, but do any of us really know what it  means to be ethical during a negotiation. I mean, we enter a negotiation with one key objective in mind – get as much for our side as possible. Where does ethics come into play when we are thinking this way? When all is said and done, do you want to feel good about what you have been able to accomplish?  

If so, then you had better learn how to conduct an ethical negotiation.
