Final answer:
NECA has local chapters across the country, providing localized representation and services similar to the IBEW's local unions.
Step-by-step explanation:
Similar to the way the International Brotherhood of Electrical Workers (IBEW) has local unions throughout the country, the National Electrical Contractors Association (NECA) has local chapters. Both the IBEW and NECA are part of the organized labor movement in the United States, which includes other prominent unions such as the National Education Association (NEA), Service Employees International Union (SEIU), American Federation of Teachers (AFT), International Brotherhood of Teamsters (IBT), The American Federation of State, County, and Municipal Workers (AFSCME), and United Food and Commercial Workers International Union. By having local chapters, NECA ensures representation and services are available to electrical contractors at a more localized level across the nation.
