Vincent Vuillemi, the Ombuds at the European Organization for Nuclear Research, has published a report covering the first year of his office's operation. Vuillemi says that he handled 82 consultations, of which 76% were CERN staff, 10% were CERN users, and 6% were fellows. In total, he assisted about 2.7% of CERN's 2,328 staff members.
Vuillemi saw almost equal numbers of men and women, but noted that given the predominance of men at the institution, women were 2.7 times more likely than men to use the Ombuds service. In addition to other statistical information, Vuillemi also identifying systematic problems and offered recommendations to CERN management. (CERN Ombuds Report 2010-11.)
