I know a thing or two about teachers union strikes. For three consecutive years, my son’s kindergarten, first-, and second-grade education was interrupted by strikes in our A-rated suburban Scranton, Pennsylvania, district. Every year, for days and weeks at a time, his schooling was completely cut off. One strike lasted several weeks, and the teachers returned to their classrooms only because they were ordered to by the court. Who knows how long the strike would have continued.
