Maestra (woman teacher) is the most common occupation of Mexican women who pursue higher education. This coincides with perceptions that teaching is a public manifestation of women's prescribed responsibility for socializing children. And yet, like women teachers elsewhere, maestras who are mothers routinely struggle to juggle their household, childcare and employment responsibilities. This ethnographic study explores the extreme work‐life imbalance experienced by rural maestras in the state of Oaxaca. Because the mountainous terrain and underdeveloped infrastructure complicate commuting, maestras assigned to isolated communities may stay in these villages while their children live with other relatives. This discussion explores ways that these women's extradomestic employment that is at odds with local ideals of the “good mother” who is at home with her children may actually help reshape constructions of maternal roles and responsibilities. Analysis of mothers' narratives reveals the emotional strains of being away from their children, and speaks to the pride these dedicated teachers take in “bringing home the milk” as economic providers. Ultimately, the tensions these agentive mothers confront and negotiate in their private and professional lives underscore ways that the prioritization of the latter in gender role norms limits women's options, choices and opportunities for full empowerment.
