 Happy he who like a teacher in an “alternative” pedagogy 
This article examines the relationship between different pedagogies and the joy of teaching. It is based on several research carried out on schools practicing alternative pedagogies as well as on experiments linked to article 34 of the « Fillon » law. Several dimensions are brought to light: the break with the ill-being experienced in traditional practices, the consistency between values and practices, the place of commitment in the history of the teacher and in his personal relationships, the professional development, the effects on students, the closer relations with families, the social recognition.
