In this research article, the authors examine the intersections of culturally sustaining pedagogy and critical family engagement to explore the possibilities for equitable family-school partnerships in urban schools. Based on the common values of trusting and caring relationships and power disruption within those fields, as well as data from a multi-year qualitative study of teachers and their relationships with students' families, the authors introduce the framework of teacher-family solidarity. The framework challenges traditional conceptions of parent-teacher relationships, and the supporting narratives of teachers and parent/caregivers illustrate that teacher-family solidarity should become an indispensable part of culturally sustaining pedagogy and practice.
