Fighting sexual harassment ranked among the priorities of the Gender Equality Plan adopted by the university Sciences Po (Paris, France) as part of the EU-funded structural change EGERA project. A comprehensive protocol was designed to monitor, report and take action about potential cases. This protocol targets all categories of users, including students, teaching staff, researchers and other staff. It aims at building an atmosphere based on mutual respect, to prevent any illegal behaviour and to offer victims or witnesses of gender-based violence or harassment a safe environment to report, ensuring the privacy of what they communicate. A monitoring unit consisting of 11 staff was established, who are in direct contact with the different categories of users of the university and the gender equality officers. The members of this unit receive training on a yearly basis. It also includes the dissemination, both in French and English, of guidelines on sexual harassment, as well as a dedicated hotline and mail address, permanently displayed on the internal information system of Sciences Po.
