This paper assesses the potential of organisational culture as a means for improving ethics in organisations. Organisational culture is recognised as one determinant of how people behave, more or less ethically, in organisations. It is also increasingly understood as an attribute that management can and should influence to improve organisational performance. When things go wrong in organisations, managers look to the culture as both the source of problems and the basis for solutions. Two models of organisational culture and ethical behaviour are evaluated. They rest on different understandings of organisational culture and die processes by which ethics are enhanced. Firstly, the prevailing approach holds that creating a unitary cohesive culture around core moral values is the solution to enhancing ethical behaviour. Both the feasibility and desirability of this approach, in terms of ethical outcomes, is questioned. The second model queries the existence of organisational culture at all, arguing that organisations are nothing more than shifting coalitions of subcultures. In this second model, the very porousness of the subcultures provides a catalyst for the scrutiny and critique of norms and practices. Such diversity and debate is construed as potentially a better safeguard for ethical behaviour than the uniformity promised by the unitary, strong culture model.
