In my entire teaching career, I was in two teacher strikes; one as a newly hired first year teacher, the other as the president of the local association. The on-the-ground specifics of every strike are different, but both experiences underlined what I have come to believe is true of all teacher strikes:

Teachers don’t want to strike.

Teacher strikes happen because teachers believe they are out of alternatives.
