Back in the United States, Arizona public school teachers are poised to strike on Thursday unless the state’s Republican-led Legislature meets their demands to strengthen public education. Governor Doug Ducey has proposed raising teacher salaries 20 percent by 2020, but unions say that doesn’t go far enough. They’re demanding similar raises for support staff; new technology; smaller class sizes; and a reversal to $1 billion in education cuts since the start of the Great Recession. The strike authorization comes on the heels of similar actions in West Virginia, Kentucky and Oklahoma, and as Colorado teachers are planning a rally Friday at their state Capitol to demand pension security and more K-12 funding.
