This is a great article by Eric Montarti and Jake Haulk of the Allegheny Institute for Public policy (Eric is a Senior Policy Analyst and Jake is the President).

The bottom line is that over half of all teacher strikes in the United States occur in Pennsylvania.  Only 13 states allow strikes, but most  include strict laws that regulate when and how long these strikes can occur.  These states also issue fines and penalties if teachers violate these laws.  However, in Pennsylvania, teachers are allowed to strike for two weeks every year with no penalty, and teachers are paid for the entire school year regardless of the length of a strike.  Such policies empower teachers and their unions while they hurt students, families, and communities.  This reality is precisely why 37 other states have made teacher strikes illegal.
