What is a trade union primarily focused on improving?

A trade union primarily focuses on improving employee pay and work conditions because its main role is to represent the interests of workers. Trade unions negotiate with employers on behalf of their members to secure better wages, benefits, and working conditions. This can include advocating for fair pay levels, safe work environments, reasonable hours, and job security. The core mission of a trade union is to ensure that employees are treated fairly and that their rights are upheld within the workplace.

In contrast, options like product costs, shareholder profits, and market competition are more related to business operations and management strategies rather than the direct interests of workers. These aspects are typically the focus of company management or economic theorists, rather than the primary concern of trade unions.
