Using ethnographic data from Welfare, Children, and Families: A Three-City Study, we examined time obligations and resource coordination of low-income mothers. Longitudinal data from 75 African American, Hispanic, and non-Hispanic White families residing in Chicago, including information on daily routines, perceptions of time, and access to resources, were gathered via participant observation and intensive semistructured interviews over 4 years. Results indicated that families constantly improvised daily rhythms to obtain and sustain resources, including child care, transportation, and social services. Participants were proactive in identifying and coordinating resources to transition from welfare to work or to maintain paid employment. Strategies used to coordinate resources and the cost associated with the inability to do so are discussed. Policy and social service recommendations are offered.
