Disagreements between colleagues, difficult relations with a customer, the announcement of unpopular decisions... Each of us must face tense and conflictual situations on a daily basis. In such moments of extreme pressure, some people give the impression of stability and self-assurance, while others are insecure, let themselves be exploited by others, and have difficulty expressing their needs and defending their rights. Why it this? In fact, the answer lies in our ability to affirm ourselves, i.e. to develop assertive behaviour? Being self-confident, knowing who you are and what you can accept or refuse... these are the best way of ensuring good and productive relations with others on a daily basis. This programme provides you with the keys for identifying and developing your potential to be assertive and for learning to use it daily.
