Saying the organization conflates criticism of the Israeli government with antisemitism, the nation’s largest teachers association on Sunday voted to boycott the Anti-Defamation League, Haaretz reported Wednesday.

A majority of the National Education Association’s 7,000-member representative assembly voted in favor of the measure, stating the union “will not use, endorse, or publicize materials from the ADL, such as its curricular materials or statistics.”

Teachers also agreed they would not participate in programs or professional development offerings from the advocacy group.

The move comes as a continuing spat between California teachers and Jewish advocates led Assemblymembers Rick Chavez Zbur and Dawn Addis to pull a bill that would penalize schools for creating antisemitic learning environments and restrict what can be taught about the Israel-Gaza conflict, according to Politico.

NEA Decision ‘Profoundly Disturbing’: ADL

The ADL has long worked in schools, promoting anti-bias and Holocaust education, according to Haaretz. More than 1.7 million students and 190,000 educators across 2,000 schools participated last year.

In response, the ADL called the teachers union resolution “profoundly disturbing.” A spokesperson called it an attempt to “further isolate their Jewish colleagues and push a radical, antisemitic agenda on students.”
