This project is part of the broader project FairHealth (https://anr.fr/Projet-ANR-17-CE26-0022) which brings together researchers from a variety of social sciences and medical disciplines to create a deeper understanding of the process by which employees' perceptions of unfair treatment - a psychological job stressor - can lead to musculoskeletal disorders (MSDs) over time. The objective of FairHealth is to study the time course of unhealthy reactions to perceived injustice, why and when injustice at work influences employees' physical health. The current project aims to determine the extent and nature of health care consumption when work situations are experienced as unfait by employees.
