The start of something big?

Maybe.

The Guardian reports more than 100 teachers in one school district have already called in sick, blunting the opening of the school year on Monday.

“We have received an overwhelming response from staff indicating that they do not feel safe returning to classrooms with students,” Gregory Wyman, district superintendent, said in a statement on Friday. …

“I’d love to see a nationwide sickout,” Kelley Fisher, an Arizona kindergarten teacher who has led protests in the state, told Reuters on Friday.

That’s one hell of a trump card the teachers just played.
