We draw on quantum physics ideas of "entanglement" and "indeterminism" to introduce and develop "Quantum Sustainable Organizing Theory" (QSOT). Quantum entanglement points to the interconnectedness of matter in ways that defy Newtonian physics and commonsense assumptions that underlay conventional organizing theory. Quantum indeterminism suggests that uncertainty is an inherent feature of reality and not simply a lack of information that impedes rational decision making. Taken together, these quantum ideas challenge the assumptions of conventional organizational theorizing about the boundaries between a firm and its natural and social environment, the importance of self-interested individualism and (sociomaterial) financial measures of performance, the emphasis on competitiveness, and the hallmarks of rational theory and practice. We discuss implications for sustainable organizing in particular and for organization theory more generally.
