The study aimed to explore ways of fostering institutional workplace environments to support sustainable academic advancement for university lecturers. This focus arose from the need to sustain the professional development of business education lecturers for improved job performance. To achieve this, the study employed a survey research design and was conducted in Cross River State, Nigeria. It was guided by two research questions and two objectives. The population for the study consisted of 150 university lecturers from the Faculty of Education at the University of Calabar. Data collection was facilitated using a structured questionnaire titled “Fostering Institutional Workplace Environments To Support Sustainable Academic Advancement for University Lecturers (FIWESSAAUL).” The reliability of the instrument was established through a pilot test, with data analyzed using the Cronbach's alpha formula, resulting in overall coefficients of 0.92 and 0.89 for the two clusters, respectively. The research questions were addressed using mean and standard deviation calculations, and data analysis was conducted with SPSS software. The findings revealed that both professional development opportunities and a supportive organizational culture significantly influence sustainable academic advancement for university lecturers in Nigeria. Based on these findings, it is recommended that university management develop and implement structured professional development programs tailored to lecturers at various stages of their careers. Additionally, it is crucial for university management to establish policies that promote work-lifebalance, including flexible scheduling, reasonable workload limits, and access to mental health resources
