My research project contributes to sustainability and ethics discussions in organisation studies by exploring personal integrity through a posthumanist lens. It aims to redefine traditional concepts of integrity to foster new approaches to ethical decision-making. The study focuses on sustainability professionals (SPs) and their complex web of relationships within organisations, where human and non-human actors are intertwined and collaboratively shape decision-making. By examining the entanglements between SPs, food, technologies, and environments, the project seeks to understand how these interconnected relationships influence personal integrity.
