Relational Inequalities focuses on the organizational production of categorical inequalities, in the context of the intersectional complexity and institutional fluidity that characterize social life. Three generic inequality-generating mechanisms—exploitation, social closure, and claims-making—distribute organizational resources, rewards, and respect. The actual levels and contours of the inequalities produced by these three mechanisms are, however, profoundly contingent on the historical moments and institutional fields in which organizations operate. Organizational inequality regimes are comprised of the resources available for distribution; the task-, class-, and status-based social relations within organizations; formal and informal practices used to accomplish goals and tasks; and internal cultural models of people, work, and inequality, often adapted from the society at large to fit local social relationships. Legal and cultural institutions as they are filtered through workplace inequality regimes steer which groups are exploited and excluded, blocking or facilitating the conditions that lead to exploitation and closure. Sometimes exploitative and closure claims-making are naked and open for all to see; more often, they are institutionalized, taken for granted, and legitimated, sometimes even by those being exploited and excluded. The implications of RIT for social science and equality agendas are discussed in the conclusion. Case studies examine historical and contemporary workplace inequality regime variation in multiple countries. The role of intersectionality in producing regime variation is explored repeatedly across the book. Many occupations and industries are examined in depth, with particular attention given to engineers, CEOs, financial service, airlines, and information technology industries.
