In this episode of Disunion, host David R. Osborne is joined by Will Sussman of the Manhattan Institute to discuss a disturbing development out of Massachusetts: the state’s largest teachers union, the Massachusetts Teachers Association (MTA), has come under fire for promoting anti-Semitic classroom materials.

Will and David break down the details of a shocking legislative hearing, where lawmakers confronted union leadership about educational resources linked to pro-Hamas propaganda and inflammatory imagery—including a Star of David made of dollar bills and posters glorifying political violence.

The conversation explores how radical ideologies have gained influence in government unions, the limits of union democracy, and how exclusive representation leaves many educators stuck with a union that doesn’t reflect their values. Will also shares insights from his own legal battles and raises a critical question: who really controls our public schools?
