With prevailing global neoliberal ideology, teachers and teacher unions must respond to market-driven governmental policies intended to undermine public education. In Saskatchewan, Canada, teacher activists feel compelled to both counter neoliberal discourses and proactively advocate for equitable, high-quality public education. To explore acts of resistance, semi-structured interviews with four teacher activists were employed to understand how teachers enact advocacy within their union and through grassroots activism. Harding et al.'s (2018) framework of alliances, assemblages, and affects informed data analysis, which included the creation of narrative vignettes characterizing teacher voice. This paper specifically discusses findings which suggest that affect, or how emotions do things, presented teachers with new potentialities for shaping educational policy.
