Tens of thousands of schoolteachers are walking off the job in Arizona on Thursday, in the state's first statewide teachers' strike. Teachers in four Colorado school districts, including two of the state's largest, are also walking out today, a day before a statewide demonstration Friday. In both states, the teachers are seeking higher pay — average annual pay in Arizona is $47,403 and in Colorado, $51,808, versus a national average of $59,660 — and increased funding for schools, after years of cuts and shortfalls. In Colorado, lawmakers are also considering changes to the state's public pension system that would reduce take-home pay. Teachers have already gone on strike in West Virginia, Oklahoma, and Kentucky this year.
