Trust is Necessary When Negotiating
In episode eight of Showtime's popular series Huff, Izzy lectures Beth on trusting too much. "You know, trust is a device we use to put people on pedestals. The higher we put them, the harder they fall". "And your point is?" Beth asks. "The next time you catch yourself trusting somebody, look at that scar!" Izzy has been deeply hurt by her husband leaving her for another woman. Beth had naively let Huff's patient into their home trusting her when she said she would not hurt anyone.
Conflict resolution, alternate dispute resolution, negotiations, mediation, settlement discussion, debt restructuring, salary and performance reviews, literally any form of productive human interaction requires a basis of trust from which accords can be reached. Humans are inclined to want to trust each other. The need to trust one another is necessary to function in society.
Honesty or integrity is an essential personal characteristic for any negotiator regardless of the situation. If you have a good reputation others will listen with confidence. If not, you will have to sell each point hard and even then may still be doubted.
Make sure you mean what you say and that you are able to back it up with your actions or those of your company. Never intentionally give your word then go back on it. Sometimes situations change and you are forced to back out of an agreement. Never do so lightly. Explain the change that occurred. Clearly demonstrate your frustration at having to change your mind to the other person. Apologize profusely and empathize with the other person's angst. Try to find a way to make it up. You do not want others to think this is typical behavior for you.
If directed by superiors to reverse your word or go back on a contract, do not blame your boss or company. Even if that is the cause, it is your word that has been broken. Taking the heat personally demonstrates your sincerity and should save a good portion of your reputation. If such vacillation is habitual in your company, consider seeking another job where you can provide proper representation.
Izzy's bitter resentment demonstrates the damage caused by a breach of trust. For her, she has lost the ability to assume people are trustworthy. When this happens in a negotiation, the absence of trust will block any chance the parties have of opening up and solving the problem. In such a situation someone needs to suggest changing the negotiators or separating them. Often a mediator will put the parties into a permanent caucus setting and negotiate between the two parties, a process called shuttle diplomacy. This tactic diffuses the angst one or both of the parties has toward the other and may allow meaningful discussions to get started. You have to be willing to get burned from time to time, as Beth was, to effectively negotiate. It requires you to have faith in the other person.
