This article draws from the concept of precarious employment to better understand the working conditions of teachers of adult English as an additional language (EAL) learners in Canada. I examine previously published research on the employment situations of this group of educators, drawing from data that have been gathered using interviews and surveys with teachers of adult English language and literacy learners over the past two decades. The findings of the review suggest that precarious employment in the form of part-time and temporary work, low wages, unpaid work hours, and multiple job holding is pervasive in this sector and that such conditions have persisted for decades. I propose that approaches developed in labour studies can assist in generating a better understanding of the ways that work insecurity affects these teachers' lives and pedagogical practices and suggest directions for further research into the intersections of working conditions and quality of education in this field. In particular, I suggest that precarious employment is produced by language and immigration policy frameworks and funding models and is linked to teacher and student identities. The article concludes by considering ways in which stakeholders can challenge employment insecurity and its associated precarity.
