WASHINGTON, D.C. – Rhonda “Randi” Weingarten, head of the American Federation of Teachers, used the occasion of the 50th anniversary of the March on Washington to take pot shots at two of her political adversaries.

In an interview with the Chicago Sun-Times, Weingarten accused Chicago Mayor Rahm Emanuel and Philadelphia Mayor Michael Nutter of betraying the goals of the civil rights movement with their recent decisions to close dozens of public schools.

“I have a big message for both Mayor Emanuel and for Mayor Nutter, which is what my 11th graders used to tell me when I taught at Clara Barton High School in Brooklyn, New York,” Weingarten told the Sun-Times. “They used to say, ‘Miss Weingarten, you can’t just talk the talk. You must walk the walk.’ Walking the walk means that you start investing in schools, not closing them, that you stabilize neighborhoods, not destabilize them.”

Weingarten continued: “So I say to both of them, shame on you. Shame on you for not actually walking the walk Martin Luther King and Bayard Rustin and A. Philip Randolph would have wanted you to walk.”

Unfortunately for the thinking public, the Sun-Times reporter failed to ask Weingarten if her union was “walking the walk” of the civil rights movement by supporting policies that keep minority children trapped inside lousy – and oftentimes dangerous – schools.

Nor was Weingarten asked how the AFT and its local affiliates are honoring Dr. King’s legacy by working overtime to keep ineffective, ignorant, lazy and predatory teachers in the classroom, thus denying children access to a quality education and safe learning environment.

And as for all the school closings in Chicago and Philadelphia, Weingarten should have been asked why her union members deserve a pass for decades of reckless financial demands that have bled those districts dry and helped cause the mass school closings in the first place.

Until Weingarten and her fellow unionists stop treating public education as a job factory for adults, she shouldn’t be casting stones at Emanuel, Nutter or anyone else.
