PhD (Public and Development Administration) / Department of Public and Development Administration / The aim of the study was to investigate the prevalence of unethical behaviour in the South African municipalities. Municipalities are responsible for providing services such as maintenance of local roads, refuse removals, water supply and sanitation, amongst others. However municipalities’ unethical behaviour have produced many disadvantages for themselves and the society at large. Effective and efficient service delivery is negatively affected by unethical behaviour resulting in the waste of government millions of rands each year, money that could have been spent on delivering services. The fact that there is unethical behaviour in municipalities can be interpreted as a total absence of ethical culture in the behaviour of municipal officials. Municipal officials are encouraged to uphold moral principles such as impartiality, accountability and trustworthy while performing their official duties. Given this background, the research project attempted to provide explanations for the patterns of unethical conduct and also pointed out strategies that could be employed to curb unethical behaviour in municipalities. For the purpose of this study, the researcher employed both qualitative and quantitative research methodologies. The researcher used purposive sampling to select respondents of the study. Two (2) instruments were used to collect data, namely, questionnaires and interviews. To analyse data, two types of data analysis were used. For data collected through questionnaires, the researcher used the Statistical Package for Social Sciences to analyse data. Data collected through interviews were analysed through the use of thematic analysis in the form of narrative. The study revealed specific unethical behaviour that were prevalent at Vhembe District Municipality. The study indicated that senior municipal officials must ensure that ethics initiatives systems and programmes should be put in place so that conducive ethical environment is created. The results indicated that despite challenges, employed strategies provided desired results. Specific solutions such improving employment practices and procurement activities were recommended that could improve ethical standards in the municipalities. / NRF
