This morning, teachers at Paul Public Charter School, one of the oldest charters in Washington, D.C., publicly announced their intent to unionize—a first for charter schoolteachers in the nation’s capital. As in other cities where charter teachers have formed unions, the Paul educators are forming their own local—the District of Columbia Alliance of Charter Teachers and Staff (DC ACTS)—which will be affiliated with the American Federation of Teachers (AFT). Seventy-five percent of Paul’s teaching staff signed a petition in support of joining DC ACTS, and asked administrators to voluntarily recognize their union.

The Center for Education Reform estimates that 10 percent of charter schools are unionized nationally, up from 7 percent in 2012. As more and more charter teachers have launched organizing efforts, the absence of charter unions in Washington, D.C., has been notable—particularly given the city’s high density of charter schools. There are 118 charters—run by 65 nonprofits—within D.C., educating 44 percent of the city’s public school students.

Patricia Sanabria, a high school English and special education teacher at Paul, is excited about unionizing with her colleagues. Born and raised in Washington, D.C., Sanabria is a product of D.C. public schools, and spent two years teaching at Ballou High School, a traditional public school in one of the poorest parts of the city, before coming to her charter.
