The U.S. Supreme Court will decide by the end of April whether to hear a case that could end mandatory union membership for all government workers.

Rebecca Friedrichs is the teacher at the center of it all.

“The union runs everything,” Friedrichs, a teacher of 27 years, told The Daily Caller News Foundation. “There’s something wrong when the majority of resources, the whole machine, is geared at serving employees, not students.”

It all started when Friedrichs, who teaches out of Buena Park, Calif., learned the union culture benefited its members at the expense of the students. Despite her disagreement with the California Teachers Association, she was forced to continue paying into it.
