Attack on teachers 'never been as bad as right now': Q&A with a teachers union leader

As another school year begins, Randi Weingarten, the president of the American Federation of Teachers, is acutely aware of how difficult the past few years have been for parents, children and teachers.

An ongoing pandemic. School shootings. Culture wars. 

"I know teachers are burnt out. I know parents are still overwhelmed. I know kids are anxious," said Weingarten, who has led the AFT, America's second-largest teachers union, representing 1.7 million members, since 2008.
