Our research work wishes to highlight the importance of the relationship between the vocal and physical behaviour of the manager and team motivation. In order to investigate this important relationship, a survey by means of a questionnaire and two field studies were undertaken. The survey has notably showed that in communication situations the working population questioned is above all sensitive to physical behaviour. The people questioned often put vocal communication in second place. It should be noted that their principal factor of motivation within the professional environment is recognition and respect for the individual. According to them, for physical behaviour, it is mainly through the eyes, followed by facial expressions and then the manager's posture that recognition and respect for the individual are expressed. With regard to vocal behaviour, these elements can be expressed through the intonation, tone and loudness of the voice. The field studies and the decision to prioritize the analysis of physical behaviour allowed us to confirm whether this body language, a sign of recognition and respect of the individual and therefore source of motivation, was a reality and resulted in a successful contact. In the working place, the way the manager looks at his team, notably, can be lacking or even absent and consequently this absence can be perceived as a closure. Therefore, if we follow our logic, this could have an influence on staff motivation. We therefore decided to complete our field studies by having the teams pass a connotation test to find out their real feelings towards their manager's behaviour. It appears that the manager's recognition for them takes second place to other equally necessary managerial qualities such as strength, endurance and a proactive personality which are widely accepted. The conclusions of the questionnaire survey have therefore been confirmed by the qualitative study. By proceeding stage by stage, our research has therefore managed to confirm the real relationship between the principal factor of motivation for staff "recognition and respect of the individual" and the physical behaviour "look, facial expression and posture" which expresses this recognition. And by really taking into consideration the relationship of vocal and visual behaviour to motivation, every manager can encourage a better quality of understanding within his team. This active listening will allow him to build a complementary and successful team by placing the right person in the right place! Henceforth, every individual's satisfaction at work becomes progressively a collective effort and a real social culture within the working place begins to grow…
