Using post-structural theories, this paper explores the public discourses of several Canadian teacher unions and grassroots teacher activist groups around the issue of school reopening plans in Canada amidst the COVID-19 pandemic. The paper aims to highlight the ways in which these two forces of teacher activism can influence and impress upon each other to create a different possible future for collective resistance to neoliberalism in education -- an assemblage of union and grassroots activism intra-acting, shaping, and impressing upon one another.
