Two lawyers who filed amicus briefs on opposite sides of the Friedrichs vs. CTA case are guests this week on a podcast called Amicus produced by Slate magazine.

Ilya Shapiro is a senor fellow in constitutional studies at the Cato Institute and Samuel Bagenstos is a professor at the University of Michigan Law School.

In the case, 10 California teachers are suing to end the requirement that they pay “agency fees” to teachers unions they have chosen not to join and which embrace positions they do not want to support.

A recent study that finds a negative effect on student achievement in states with laws that support teacher collective bargaining is cited in the podcast. That study, “A Bad Bargain,” by Michael Lovenheim and Alexander Willen, appears in the Winter 2016 issue of Education Next.
