Assertiveness can be defined as expressing, in a friendly and respectful way, what you want to limit on a certain matter, either an opinion that goes against that established by the other participants in the conversation or, well, contributions to enrich the chat. This is also the knowledge and defense of one's own rights, also respecting the existence of others; Assertiveness starts from the premise that people have a series of basic or assertive rights, which must be preserved, regardless of the circumstances in which the person finds himself.
Assertiveness, as a negotiation technique to get what you want, uses persuasion, produced by the charm that a passive and friendly person generates in the community. This is also a way of saying "no". As such, it is composed of a series of techniques, in which the individual is educated to be frank, honest, open and direct about the matters that concern him. In this way, assertiveness is summarized in a behavior that combines both passivity, that attitude in which third parties are left to decide for their own destiny, and aggressiveness, when it is not the object and the opinions of other people may be disrespected.
Various studies have been carried out, trying to unravel the details that make other people assertive and others not. Andrew Salter, around 1940, determined that this is a characteristic of the personality, so that some individuals have it and others do not; Furthermore, he related his presence to the degree of maturity of the person, as well as the prevailing ideologies, self-esteem and lack of character.
