Caliber Public Schools, with 1,700 students on campuses in Richmond and Vallejo, recently recognized a new union formed by its teachers and staff, according to the Vallejo Sun.
The union is part of the Industrial Workers of the World, also known as the Wobblies. According to the Sun, Caliber workers are the first in the United States to join the IWW.
The Caliber charter school network includes two TK-8 campuses and is growing. Teachers said they wanted to unionize to have more influence over school management, to reduce class sizes and improve working conditions.
