Book reviewMaster discourses on age and our acts of organizing around age and ageing overshadow more complex, non-essentialist enquiries in management and organizational studies. Hearn and Parkin (2021), in their book Age at work: Ambiguous boundaries of organizations, organizing and ageing, focus their efforts on deconstructing these master discourses thereby opening the door wider to considering non-essentialist enquiries around age(ing) intersecting with organizations. In the process, they answer Aaltio et al.'s (2017) call for a closer look at the discursive nature of age(ing). Notably, Hearn and Parkin consider the boundary states of age(ing) in society and in organizations, and how such master discourses impact the production and sharing of academic knowledge. They also reflect on an important rigid practice that continues to be reproduced; that is, (gendered/racist/classist/etc.) ageism in organizations and in broader society persists as one of those discriminatory practices that we seem not prepared to undo "just yet".Their book is divided into four parts, where they along with Richard Howson and Charlotta Niemist€ o address many if not most key concepts and, with the material-discursive theoretical framework, investigate age(ing) in society and age(ing) in organizations. They also look at notions surrounding what they call "a living afterlife", where "the power of the individual is diminished [. . .] major decisions are removed to others [. . .] [and] people can feel powerless and superfluous" (p. 128), along with deconstructing death and post-death concepts and experiences. They set the stage for the post-graduate reader in each of the introductory chapters (One, Two, Four and Six) to each of the book's four parts, talking explicitly to the construction of such concepts as age and ageing, generations and life course, and ageism in its many different facets (Chapter One), along with age systems, societal age regimes, social structure organizing and age hegemony (Chapters Two). The authors also guide the reader from social relations' contingency to intersectionality scholarship and onto the theme of intersectional age and the accompanying silences about these complex intersections that lead to the exclusion of old(er) individuals in their third age (i.e. those who have active engagement in formal organizations, whether paid or unpaid) or fourth age (i.e. those who are dependent, marginalized and potentially isolated) (Chapters Two, Four and Six). They also consider historicity, power relations, age hegemony and relations to social structures, pulling on various kinds of literature studies on age(ing), where they call out that to understand age more fully there is a need to push beyond history to historicity, where the latter is not the same as either history or histories [. . .] [historicity is] to move beyond the appearances of truth organized into essentialist categories, the focus is less on identifying "what is" and more on the "why it is" (p. 43).
