It’s important to understand that workers don’t hire a union, or bring in a union, they join together with their co-workers to form a union. The reason they do this is because it’s the only means workers have to compel their employer to bargain with them in good faith for a written contract. The IBEW has experienced representatives and negotiators to lead the way, but the issues proposed by the union during negotiations are those the workers themselves bring forward. You’re forming a union to accomplish as a group what you can’t as individuals.
