The American Federation of Teachers says a "decisive majority" of teachers have filed a petition with the NLRB to have a union election at Cesar Chavez Prep Middle school in Washington, D.C.

It's the result of a two-year organizing effort by the AFT. If the union wins the election it will be the first charter school in D.C. to become union.

The AFT represents educators at 231 charter schools in 15 states around the country.

The union says the teachers with their si, se pude - or yes we can - attitude are standing up to win more resources for the charter school kids, a real teacher say in school decision-making and job security.

The teachers have formed the District of Columbia Alliance of Charter Teachers and Staff.

Christian Herr, a sixth-grade science teacher at the charter school says,"We hold up examples of great community organizers like Cesar Chavez and Martin Luther King Jr., and encourage our students to follow in their footsteps in order to make their communities better.

What better way to teach our scholars how to do this than to show them?"
