Background: Social movement scholarship tends to focus on macro-level processes of movement emergence, overlooking the day-to-day groundwork of marginalized social movement actors who contribute to and sustain large-scale action. Contributing to this gap in literature, we develop the construct of "pedagogies of organizing" to illuminate the micro-level dimensions through which social movements for educational justice emerge. Methods: Drawing on audio/video recordings, field notes, and artifacts as data, we examine the micro-interactional processes through which a teacher of Color, as union organizer, facilitates common cause and identity among teachers, students, and working people as social movement actors in the 2019 Los Angeles teacher strike. Findings: Our analysis details how broad-based social movements and teacher union's organizing strategies influenced his practices. Guided by ethnic studies and third world feminism, this teacher simultaneously engaged multiple contexts--sometimes at tension with one another--to (re)create organizing strategies that sustained collective action and (re)centered anti-racist intersectional visions of educational justice. Contribution: We argue that this teacher's culminating practices concurrently re-shaped and re-imagined present and future education reform efforts, and discuss how expansive possibilities of educational justice within a neoliberal context are embodied by teacher-activists of Color who critically and innovatively enact everyday organizing practices.
