IT workplaces can become hostile or even toxic environments for women. Not only are they more male-dominated than other types of firms but they also tend to be governed by “cultures of engineering” in which male technical prowess is an organizing principle for social relations. The following project seeks to expand on this important theoretical field to address the implications of these cultures of engineering in an increasingly global era. Little attention has been directed, first of all, to the issue of whether there might be different kinds of discriminating environments across national contexts. Common types of discrimination experienced by women engineers in the Global North may be less prevalent in other parts of the world. Moreover, there may be hidden advantages for women engineers in Global South settings, which are useful in alleviating tensions in the Global North, and vice versa. Second, there has been surprisingly little research attention given to the global dynamics of IT workplaces, even though the high tech industry is in a stage of rapid change.   Global Circuits of Gender- Women and High Tech Work
