Based on the meaning-making of women geoscientists in their descriptions of work and career experiences, this article explores the gendering of geoscience by analyzing women's hard work as a theoretical concept. Our findings show that the gendered requirements for women in geoscience involve “doing” various forms of hard work, including making one's work visible, asserting one's physical performance, and building social relations. Thus, hard work is found to be gendered in terms of being a perceived requirement shared by female geoscientists. It is a requirement that entails compensating for not being male in masculine organizations and simultaneously prevents women geoscientists from fully engaging in core geoscience work tasks. Hence, by gendering hard work and theoretically defining hard work as the work of the “other”, the study expands the theoretical understanding of the concept by suggesting that women's hard work is gendered and social rather than productive.
