Have Teachers Unions Really Lost The Backing of The Press?

This Wall Street Journal opinion piece says yes:

Quick: Which newspaper in recent editorials called teachers unions "indefensible" and a barrier to reform? You'd be excused for guessing one of the conservative outlets, but it was that bastion of liberalism, the New York Times. A month ago, The New Yorker—yes, The New Yorker—published a scathing piece on the problems with New York City's "rubber room," a union-negotiated arrangement that lets incompetent teachers while away the day at full salary while doing nothing. The piece quoted a principal saying that union leader Randi Weingarten "would protect a dead body in the classroom."

Things only got worse for the unions this past week.
