A more thorough explanation:

Definition: Industrial unionism is a type of union organizing that brings together all workers in a particular industry into one union, regardless of their specific skills or trades. This allows workers to have more bargaining power and strength in strikes. It is different from craft unionism, which organizes workers into separate unions based on their specific trades.

• United Auto Workers (UAW) - represents all workers in the automobile industry, including assembly line workers, engineers, and office staff.
• International Brotherhood of Electrical Workers (IBEW) - represents all workers in the electrical industry, including electricians, linemen, and technicians.

These examples illustrate industrial unionism because they bring together all workers in a particular industry, regardless of their specific skills or trades. This allows the union to have more bargaining power and strength in strikes, as all workers in the industry are united and working towards the same goals.
