University of Denver leaders cut jobs and are tightening the school’s budget amid what Chancellor Jeremy Haefner is calling “a very difficult time for the university.” The private research university is facing waning enrollment that has left the institution with an $11 million budget deficit, according to school officials. As a result, DU eliminated eight administrative staff positions this fall — three in the College of Arts, Humanities and Social Sciences and five more across the campus, including in the chancellor’s office, University College and the Josef Korbel School of International Studies. Additionally, 15 staff positions in the College of Arts, Humanities and Social Sciences will be replaced with higher-paid roles that will serve all 20 departments.
