This article uses Acker's theory of gendered organizations to frame an analysis of the ways in which policies and practices in a men's and a women's prison reflect and reproduce gendered inequalities. The article offers a working definition of one of Acker's key theoretical concepts, the notion of “gendered organizational logic.” Then, using interview data collected from correctional officers in a men's and a women's prison, the article examines the ways in which officer training and assignments, although designed to be (...) nominally generic, assume a male worker and disproportionately benefit male officers working in men's institutions. These findings imply that the perspective could more usefully be conceived as a theory of “masculinized” organizations. (shrink)
