Which type of union aims to represent workers across multiple industries?

The correct choice is an industrial union because this type of union seeks to represent workers from various industries under a common banner, usually based on their function or interests within the workforce, rather than their specific skill or trade. Industrial unions advocate for the rights of all workers within multiple sectors, allowing them to organize collectively regardless of the specific industry in which they are employed.

This broad focus allows industrial unions to address broader labor issues, negotiate for better working conditions, wages, and benefits that affect workers across many different fields. For example, workers from manufacturing, service, and transportation sectors can unite through an industrial union, giving them greater collective bargaining power.

In contrast, trade unions typically represent workers within a specific industry, focusing on trade-specific issues. Craft unions, like trade unions, are organized by specific skills or trades, concentrating exclusively on the interests of those particular skilled workers. Professional unions, often found in fields like education and healthcare, represent individuals based on their professional roles rather than cross-industry representation. Therefore, the distinction lies in the industrial unions' capacity to unite diverse workers across multiple sectors, while other unions tend to represent more specialized groups.
