Correlation Between Mental Health, Performance and Productivity in Educational Workplaces

Mental Health and Wellness for Efficiency in Education

Abstract

Mental health has become one of the most critical determinants of productivity in the workplace, with strong evidence linking poor mental health to absenteeism, presenteeism, and reduced performance. These effects are even more visible in educational institutions, where the quality of teaching and research depends on staff wellbeing. Global surveys have shown that depression and anxiety contribute to losses estimated at over a trillion dollars annually, and the burden is expected to rise if not addressed. At the same time, Sub-Saharan Africa, including Eswatini, faces additional challenges such as limited resources, cultural stigma, and shortages of professional support services.

This paper presents a critical literature review of studies published between 2020 and 2025 that examine the relationship between mental health and workplace productivity. The review identifies key workplace drivers of poor mental health, including heavy workloads, job insecurity, lack of management support, and stigma, while also recognizing protective factors such as supportive leadership, employee assistance programs, and flexible work arrangements.

The findings suggest that institutions can play a decisive role in protecting staff wellbeing by adopting mental health policies, creating awareness programs, and providing access to professional services. While evidence from high-income countries is encouraging, there is a clear gap in research focusing on Sub-Saharan African universities. The review therefore concludes with a call for more locally relevant studies and for institutions to implement targeted, context-sensitive interventions to improve staff wellbeing and sustain productivity in higher education.
