This study analyses the attitudes of university students towards unethical behaviour in the individual and organisational environments, and relates these attitudes to tolerance of corruption in their future professional lives. The results show a positive relationship between attitudes towards unethical behaviour in both environments, as well as tolerance towards acts of corruption, based on a virtual perception survey. Despite the general rejection attitude by students of such behaviour and acts, the rejection diminishes as their degree programme progresses. This study contributes to our understanding of the tolerance of university students towards corruption, and to revealing how this attitude could explain tolerance towards this phenomenon in their future professional lives.
