摘要：Purpose: The purpose of the study was to investigate the influence of transformational leadership, organisational citizenship behaviour and quality of work life on job performance amongst supply management professionals employed by the South African government. Rationale: The depressed job performance of supply management professionals in the South African government presents an impetus to generate new empirical information on the subject in order to find solutions. Methodology: A quantitative survey approach was followed using a sample of 264 supply management professionals employed in the South African government and were based in Gauteng Province. A Confirmatory Factor Analysis (CFA) was conducted to assess psychometric properties of the measurement instrument. Hypotheses were tested using Structural Equation Modelling (SEM). Findings: Transformational leadership had positive and significant relationships with organisational citizenship behaviour and quality of work life. Quality of work life exerted a greater influence of job performance than organisational citizenship behaviour. Value of research: The study provides current evidence of the influence of transformational leadership on organisational citizenship behaviour and quality of work life, as well as the influence of organisational citizenship behaviour and quality of work life on job performance amongst supply management professionals. Conclusion: Transformational leadership has a positive influence on organisational citizenship behaviour and quality of work life amongst supply management professionals in the government. Both organisational citizenship behaviour and quality of work life exerta positive influence on the job performance of supply management professionals in the government. Future studies should be extended to other professional cohorts in both the private and the government sectors.
