MCom / Department of Human Resource Management and Labour Relations / The objective of this study was to investigate the effects of workforce diversity on employee performance in a selected Higher Educational Institution in South Africa. Various legislative measures were introduced by the government in order to shape the workforce in organisations. However, these legislative measures expressly focus on compelling organisations to embrace diversity and thus not considering the business need of it and how it influences employee behavioral outcomes such as employee performance. It is upon this backdrop that this study investigated the effects of workforce diversity on employee performance in an HEI in South Africa. A cross-sectional research design was used. A random sample (n = 267) was chosen by dividing employees into homogeneous strata of academic and non-academic employees. A Workforce Diversity Questionnaire and Employee Work Performance Questionnaire were administered. The results showed a positive and significant relationship between independent variables (gender diversity, ethnic diversity and educational diversity) and the dependent variable (employee performance). The relationship between age diversity and employee performance was not significant. HEIs should introduce diversity management programs to improve the effectiveness of workforce diversity towards employee performance. Because a cross-sectional research design was employed, conclusions about causality could not be made
