 Representations of the secondary school teacher’s job, before and after a working experience: From the transmission of knowledge to the taking into account of trust-based relationships 
Teachers usually consider their work as the opportunity to transmit knowledge. A recent research conducted with secondary education teachers, before they start teaching and after a teaching experience, shows an evolution where the necessity of maintaining some fulfilling teacher-pupil relationships surfaces, in which feelings of mutual trust would be key. In addition, pedagogical methods are undergoing a tremendous change in which digital technologies play a key role. This research investigates the possibility of assessing teaching satisfaction today in view of the teachers’ professional development who face unpredicted socio-educational issues when they enter the career. Therefore, the manner the professional identity is submitted to a subjectivation process depends on the sense granted to the teaching activity, based upon its usefulness. In that way, teaching could be related to a feeling of happiness.
