UEU serves the educators and staff of the UNO Charter School Network. In 2013, UNO voted to unionize, in order to improve conditions for educators, students, and families. The first contract was ratified in spring, 2014. Union leadership collaborates with the Network on a variety of issues, including calendar, contract, curriculum, and working conditions. UEU currently represents over 500 members, and all elected officers and representatives are current teachers and staff.
