As numerous states — most prominently Wisconsin and Ohio — consider curtailing the collective bargaining rights of their workers, the debate has largely focused on money and power. If public employee unions are de-authorized or restricted, what impact will that have on state budgets? Tax rates? Political contests?
When it comes to teachers, however, this discussion bypasses a crucial question: What is the impact of collective bargaining on students? A study just published in the Yale Law Journal, which looks at recent, real-life experience in the state of New Mexico, provides a troubling answer.
It finds mandatory collective bargaining laws for public-school teachers lead to a welcome rise in SAT scores – and a disappointing decrease in graduation rates. Author Benjamin Lindy, a member of the Yale Law School class of 2010 and former middle-school teacher, reports that any improvements in student performance appear to come “at the expense of those who are already worse off.”
