Therefore, discretionary behaviours such as OCB among employees in such organizations like any other organizations are crucial for organizational effectiveness and performance. Thus, improving the organizational citizenship behaviours of employees in such organizations in order to promote organizational effectiveness, performance and success is one of the fundamental challenges and principal tasks facing managers. The primary aim of this study is to examine and understand the influence of transformational leadership and organizational climate on organizational citizenship behaviour among support staff. The secondary objective is to make recommendations to organizations on the importance of transformational leadership in promoting OCB thereby providing recommendations to OD and HR practitioners on the best practice on the pro-organizational behaviour. The quantitative research design was used in the study. The target population for this study were the support staff at the selected university in the Western Cape Province. The population size was approximately 1123. A sample size of 220 was drawn using the Rasoft calculator. An online Google Form Questionnaire (instead of hard copy questionnaire as originally planned) was administered to a sample size of about 220 working support staff. Convenience sampling methods were used to reach the desired number of responses. The Multi factor Leadership Questionnaire (MLQ SX) was used to measure transformational leadership, Organizational climate questionnaire (OCQ) for measuring organisational climate and the Organizational Citizenship Behaviour scale (OCBS) for measuring organisational citizenship behaviour. Data was analysed using structural equation modeling. Item and dimensional analyses were performed to determine the quality of the items. Significant relationships were found between transformational leadership and organisational citizenship behaviour; organisational climate and organisational citizenship behaviour and transformational leadership and organisational climate. The practical implications and recommendations for future studies were provided.Transformational leadershiporganizational climateorganizational citizenship behavioursupport staffstructural equation modelingThesis
