You said "it really is about the longer school day and that is about that."
I presented several more issues the teachers are concerned about. Then you say I'm telling you the strike is about libraries? Huh?
I visited Whittier School last year when I was in Chicago. The parents there were occupying a building on the school grounds and had turned it into a library full of their own children's books. It was one of the saddest things I had ever seen in my life. And you live in Chicago and you didn't KNOW about this?
Nearly one in four Chicago public elementary schools and more than fifty high schools don't have staffed, in-school libraries. Parents at one school were so incensed, they occupied a school building for more than a month to pressure city officials to add one. School officials say they value libraries, but in an era of tight budgets, they often lose out to other priorities.

Maybe you should try actually talking to teachers there. That's where I get my information. I figure the ones who actually voted to strike would know why the vote was taken. Just a hunch.
