Purpose: Prior research reveals that teachers have lower job satisfaction when they have more Black students, but this work does not consider how different aspects of work conditions - and the increasing diversity of students beyond a Black/White binary - may matter. This study aims to examine the relationship between teachers' perceptions of work conditions and the racial/ethnic compositions of the classes they teach. Design/methodology/approach: This study leverages data from the Measures of Effective Teaching (MET) study. Analyses consist of both descriptive statistics and multilevel regression modeling. Findings: Findings show that teachers' satisfaction with working conditions varies in relation to the racial/ethnic composition of their students. Increase in the percent of Black, Latinx and Asian American students in a teacher's classroom, was associated with a decrease in satisfaction with community involvement and student behavior. For increase in Latinx and Asian American students, this study finds significant decrease in satisfaction with measures of pedagogical and job support. For measures of school leadership and responsiveness to professional development needs, this study sees no significant relationship, which suggests that perceptions of some working conditions are more strongly tied to classroom demographics than others. Originality/value: This work adds nuance to previous research on teacher job satisfaction by exploring satisfaction with various working conditions and how it varies in relation to classroom racial composition. This study concludes with a discussion of potential explanations for observed differences in teacher satisfaction, as well as potential ways to address these differences.
