In 2002, Sally Lee found out about a group of teachers meeting to act on political issues (motivated by Iraq War protests) and went to their first open meeting. She joined the group and after some initial work, the group named itself NYCoRE (New York Collective of Radical Educators). Sally and fellow NYCoRE member Herm Jerome eventually initiated a study group and work group around issues of criminalization of youth.

After leaving teaching in 2003, Sally continued to work with NYCoRE and started planning Teachers Unite to marry the world of teachers for social justice to the world of rank-and-file UFT activists, and to build a center for social justice teacher organizing. Herm Jerome was a founding board member. After getting involved with the Student Safety Act Campaign, Teachers Unite partnered with NESRI and in 2008 published Teachers Talk: School Culture, Safety and Human Rights.

In 2011, through collaboration with NESRI and Dignity in Schools Campaign member organizations, TU received enough funding to hire a community organizer. TU’s work building Restorative Practices and contributing to the Dignity in Schools Campaign was able to deepen and expand.

In 2012 Teachers Unite embarked on the Growing Fairness project, which led to the formation of a cadre of lead members building transformative justice resources with an eye toward leadership development, school organizing, and movement building.
