Property is pervasive, and yet we organization scholars rarely discuss it. When we do, we think of it as a black-boxed concept to explain other phenomena, rather than studying it in its own right. This may be because organization scholars tend to limit their understanding of property to its legal definition, and emphasize control and exclusion as its defining criteria. This essay wishes to crack open the black box of property and explore the many ways in which possessive relations are established. They are achieved through work, take place as we make sense of signs, are invoked into existence in our speech acts, and travel along sociomaterial networks. Through a fictionalized account of a photographic exhibition, we show that property overflows its usual legal-economic definition. Building on the case of the photographic exhibit, we show that recognizing the diversity of property changes our rapport with organization studies as a field, by unifying its approaches to the individual-vs.-collective dilemma. We conclude by noting that if theories can make a difference, then whoever controls the assignment of property – including academics who ascribe properties to their objects of study – decides not only who has or who owns what, but also who or what that person or thing can be.
