Drawing on the example of Médecins Sans Frontières (MSF), Françoise Duroch and Emmanuel Noyer review the measures taken by the non-governmental organisation (NGO) to combat sexual violence. The authors show the moral relativism that runs through humanitarian organisations concerned with preserving their public image. Admittedly, the latter are increasingly aware of their obligation to monitor the behaviour of their employees, but the systems need to tackle inequalities, especially gender-based ones. For the authors, NGOs will only achieve this by integrating intersectional approaches.
