[Workplace's evolution and mental burn-out in the agricultural sector].

The article describes the evolution of working conditions in the agricultural sector in Brittany and its repercussions on agricultural workers' health. Based on personal accounts of local rural workers' experiences, the authors demonstrate that it is not necessarily the introduction of new working methods and means, but rather the speed at which they are introduced and implemented that is responsible for the emergence of mental health problems and psychological vulnerability. Furthermore, this process contributed to the identity crisis of those farmers who did not identify with the new professional schema in order to incorporate the new techniques. Recent observations of farmers' conditions show that this phenomenon is perpetuating and evolving.
