Union activity does not only influence unionized workers – it meaningfully impacts other workers too.
Interesting article. I recently read a study on teachers’ unions. It found that when union power was reduced in the public school system, student attainment generally went up. It also found evidence that teachers unions tended to overpromise and strain budgets by spending down reserves more quickly and then seeking tax hikes to pay for them.
This is, of course, perhaps a difference between unions in the public and private sectors. I will be incorporating these findings into an upcoming essay.
