Chicago International Charter School teachers vote to authorize strike

CHICAGO — By an overwhelming majority, Chicago International Charter Schools teachers have voted to authorize a strike.

The teachers are still negotiating their contract, so a strike date isn't set.

Teachers that work in the Acero network, the largest charter school operator in the city, voted Tuesday to authorize a strike.

They're calling for more pay, smaller class sizes, improved resources and extended parental leave.

If they strike, they'll become the first group of charter school teachers in the country to walk the picket line.

Contract talks resumed Friday.
