How many local chapters are required at a minimum to establish a federation or national union?

To establish a federation or national union, a minimum of ten local chapters is required. This requirement is rooted in the idea that a sufficient number of local chapters can ensure representation from different regions and industries, thus providing a broader base of support and influence. With ten local chapters, the federation can effectively demonstrate its capacity to represent a diverse range of workers and interests, which is vital for negotiations, advocacy, and strengthening collective bargaining power. Fewer than ten chapters may not provide adequate representation or resource diversity needed for a robust national organization.
