Nearly one in five teachers have now broken ranks with OEA.

Corey DeAngelis:

Until 2018, Oregon was one of 23 states without right-to-work protections for government workers, meaning teachers and thousands of other public employees were required to financially support union activities.

That changed in 2018 when the U.S. Supreme Court, in Janus v. AFSCME, affirmed that mandatory union payments violate public employees’ First Amendment rights.
Knowing members could suddenly walk away without losing their jobs, OEA and other government unions could have responded by simply working harder to provide a service worth paying for. 

But of course, that is not what happened.
