Being assertive is not the same as being aggressive. How to be assertive is one of the most important interpersonal skills anyone can have. It allows one to be treated as an individual and with respect, and at the same time get things done without having to resort to coercion or be submissive, responding like a victim. Assertiveness does not necessarily mean you must say no. It does not mean you must always have your way. It is a positive way of interacting, actively listening to mutual needs, stating situation in an objective manner, expressing your feelings and requirements, helping the other party understand the consequences, so that a decision can be reached in a manner that is beneficial to both parties. It is about stating your own needs and wants without aggression.
Effective assertive skills reduce tension, minimise conflicts and improve productivity because communication among team members can be more open, direct and focused on issues, without having to rely on ploys to achieve hidden agenda.
