Unethical behavior in organizations has garnered more and more attention in the last decades but most of the scholarly work has used a static approach relying on methodological individualism and a mechanistic worldview when studying this topic. The process of moral disengagement and organizational culture have been linked to the prevalence of unethical behavior earlier, but this paper uses a complexity-informed systems perspective to explore the dynamic relationship of these concepts and aims to improve our understanding of the often unnoticeable, (...) step-by-step process through which organizational cultures can become conducive to unethical behavior. Organizations are conceptualized as complex adaptive systems in which transformative and stabilizing processes based on feedback loops take place continuously. It is discussed how these processes can lead to a phase transition driving organizations towards a state where unethical behavior is the general norm. The process is illustrated through real-life examples. (shrink)
