Yes, administrators can decide to move to the classroom and stay in the NSTU, or stay in their current role and move out of the union. As long as the association is affiliated with the NSTU, administrators will be able to move between the association, as an administrator, and the union, as a teacher, any year, not just the first year, while having their seniority protected.
