Teachers are leaving jobs in growing numbers, state reports show. The turnover in some cases is highest among teachers of color. A major culprit is stress — from pandemic-era burnout, low pay and the intrusion of politics into classrooms. But the burdens can be heavier in schools serving high-poverty communities that also have higher numbers of teachers of color. Nationally, about 80% of American public school teachers are white, even though white students no longer represent a majority in public schools.
