Revisiting Joan Acker's work with the support of Joan Acker

This article is a personal tribute to working with Joan Acker. I worked with Joan in 2012, helping to edit her own thoughts and reflection on how other academics evaluate and used her own theorizing, specifically her seminal work on the gender substructure and inequality regimes. However, while this article is a tribute to Joan, her work and her thinking; it is also a personal thank you to someone I will miss for her generosity and also her activism in challenging inequalities in organizations and beyond. She continues to inspire me and hopefully others to challenge for social justice. In her 80s, Joan remained committed to addressing inequalities in social relations and how these were experienced within a dynamic social and work environment. During our collaboration, she called upon academics to put theory into practice to help address visible and invisible inequalities in organizational processes. This article is inspired by that experience and it will reveal Joan's views about her own, and other academics, theorizing of her two key concepts: the gender substructure of organizations and inequality regimes in organizations and the overlap with intersectionality. This article will offer a unique opportunity to gain insight into Joan's thinking as an academic sociologist as well as a feminist activist thereby uniting Joan as a person with her concepts.
