Eventually, both sides might not able to come to an agreement.
The second type of negotiation style is submissive. It is exactly the opposite of aggressive. Instead of demanding what you want, you comply with what other parties want. Basically, the behaviour involves agreeing with most - if not all - demands from the other parties. Usually, a submissive negotiator will say, "Ok, we will do that.", "If you insist, then I guess I'll have to do it then.", "Sure, no problem." etc. Being submissive during negotiation can benefit the user in certain ways. One of them is induce sympathy on the other parties. As you being submissive toward the demands from the other parties, they might started to think that they being too demanding, and should comply with your request as a return of favour. One point has to be noticed is that, being submissive does not equal to a display of weakness. Instead, it could be a method to ensure a better flow of negotiation. For example, the other parties demand something from you and the requests are not over demanding, or what they requested are also what you want, then it is suitable to display a submissive behaviour as it allow the negotiation to continue to move on to next objective, without causing much disadvantage to yourself.
Being submissive in negotiation comes with a price too, just like being aggressive in negotiation. Facing with certain more aggressive parties, they might take advantages toward more submissive negotiator. They will display less sympathy toward you, and take for granted whenever you comply to each and every of their requests. The negotiation might end, both side might come to an agreement, but in the end you will give more than what you get as you had being taken advantage for being over submitting.
The last negotiation style is assertive. Basically, it is combination of both aggressive and submissive. An assertive negotiator will request something from the other parties, by offering to do something else in return, and vice versa.
