This study investigates job satisfaction among non-academic staff at the Institute of Finance Management (IFM) in Tanzania. It uses Herzberg’s dual theory to identify motivational and hygiene factors that influence job satisfaction among administrative staff at IFM. A mixed-methods approach was employed: collecting data through semi-structured questionnaires, interviews, and Focus Group Discussions (FGDs) with six participants from four departments. Out of 85 questionnaires distributed, 67 were returned, yielding a 79% response rate. Data were analyzed using SPSS and content analysis. The findings revealed that satisfaction was primarily driven by relationships with co-workers (64%), job security (55%), and responsibility (51%). Moderately favorable factors included achievement (46%) and recognition (43%). Conversely, staff expressed dissatisfaction with promotion opportunities (73%), work conditions (70%), and salaries (67%), citing long-standing inadequacies that have been diminishing their morale. Ambivalence was reported regarding supervision (48%) and institutional policies (63%). Respondents recommended that the Human Resource Management (HRM) office should ensure equity in staff promotions, addressing concerns that current practices disproportionately benefit academic staff over administrative staff. Additionally, they suggested improving incentives, such as extra duty allowances, transport, and housing allowances. They also addressed salary inadequacies, especially in light of rising living costs, loan repayments, and tax deductions. Enhancing work conditions was also highlighted as a critical area for improving job satisfaction. This study underscores the need for targeted management interventions to address dissatisfaction and enhance administrative staff satisfaction, ultimately contributing to institutional success
