According to an op-ed in this morning's Wall Street Journal, Pennsylvania has the highest incidence of teacher strikes in the country. In fact, 110 school districts are at risk of teachers going on strike in the next 6 months. PA apparently has the ninth highest average teacher salary in the country--$54,970 in 2006-2007. Other interesting facts: 42% of the country's teacher strikes occur in the Quaker State and carry no consequences for teachers or unions (some states fine unions for strikes or make teachers give up salary for days missed). Worst of all, in 2007-2008, kids who were chucked out of classrooms while teachers were on strike were on these strike-vacations for an average of 13 days. That's a lot of school days to miss!
