This study examines the links between antecedents and consequences of Gabonese teachers' work motivation (N= 152). The theoretical underpinnings are based on the Motivational Model of Job Burnout (MMJB) and Self- Determination Theory (SDT) which states that the more supervisors will satisfy employee's needs for self-determination, competence, and relatedness, the more their work motivations will be self-determined. The latter will then have an impact on job satisfaction that will then determine life satisfaction. Higher levels of Self-determined motivations will also generate lower emotional exhaustion and psychological distress. The model was confirmed via structural equation modeling and provides support for the validity and generalizability for the MMJB and SDT.
