The nature, causes, and effects of occupational stress on academic lecturer performance in private tertiary institutions located in Gaborone, Botswana

Abstract

This study investigated the nature, causes, and effects of occupational stress on academic lecturer performance in private tertiary institutions located in Gaborone, Botswana. The backdrop to this research is a higher education sector increasingly characterized by rising workloads, resource limitations, and growing performance expectations placed on lecturers. These factors have raised concerns about the impact of stress on both individual well-being and institutional effectiveness. Adopting a convergent parallel mixed-methods research design, the study combined quantitative survey data from academic staff with qualitative insights obtained through open-ended responses. The quantitative component utilized structured questionnaires distributed to academic staff and managers across private tertiary institutions in Gaborone. From a target population of 1,173 academic staff and managers across 14 registered private tertiary institutions, a sample of 294 respondents was selected, of which 255 valid responses were obtained, representing an 86.7% response rate. Descriptive statistics, correlation analysis, and regression models were used to assess the extent of occupational stress and its impact on various dimensions of lecturer performance, including teaching quality, productivity, student engagement, and deadline compliance. Qualitative data were analyzed thematically to capture deeper personal and contextual narratives around stress experiences. The findings revealed that occupational stress is both prevalent and multidimensional in nature. Major stressors included excessive workload, time constraints, role ambiguity, administrative overload, and insufficient institutional support. Quantitative findings showed statistically significant negative relationships between occupational stress and lecturer performance, with correlation coefficients ranging from r = -0.68 to r = -0.72 across key performance dimensions. Regression analysis further showed that occupational stress predictors explained 58% of the variance in lecturer performance (R² = 0.58), with emotional exhaustion and lack of role clarity emerging as the strongest contributors to reduced performance. Qualitative findings reinforced these results by highlighting lecturers’ experiences of fatigue, frustration, reduced motivation, and challenges in balancing teaching, administrative, and personal responsibilities. The study concludes that occupational stress in Botswana’s private tertiary institutions is not merely an individual challenge, but a structural issue embedded in organizational culture, management practices, and institutional governance frameworks. Based on these findings, the study recommends that private tertiary institutions review lecturer workloads and role allocations, establish staff wellness and psychosocial support programmes, strengthen communication and managerial support systems, and embed stress management and emotional well-being interventions within staff development and human resource policies. The study further underscores the importance of inclusive leadership, staff participation in decision-making, and sustained investment in academic support infrastructure. This study contributes to the growing body of literature on higher education in emerging economies, particularly within the SADC region, by providing empirical evidence on the relationship between occupational stress and lecturer performance in Botswana’s private tertiary education sector. It offers practical insights for policymakers, institutional leaders, and scholars interested in academic workforce sustainability, and opens avenues for future research, including longitudinal investigations into stress across academic career lifecycles and comparative analyses between public and private tertiary institutions.
