Which of the following is NOT a responsibility of local IBEW unions?

The option referring to handling international diplomacy is correct because local IBEW unions primarily focus on issues and responsibilities that are relevant to their member electricians and the specific labor markets they serve. Their main functions typically include managing relations between employers and employees, participating in contract negotiations, and recruiting and organizing new members within their local context.

International diplomacy, on the other hand, involves broader, global-scale interactions and negotiations, which are usually handled at the national or international level rather than by local unions. Local unions are more concerned with the immediate needs and concerns of their members and ensuring fair labor practices within their local jurisdictions. Their work revolves around collective bargaining, workplace conditions, and member services rather than navigating international relationships or policies.
