Which function does a trade union NOT perform?

A trade union primarily aims to protect and enhance the welfare of its members, focusing on collective bargaining and negotiating with employers for better terms and conditions at work. While trade unions often advocate for their members' rights and voice their concerns about working conditions, they do not typically provide legal representation in court as a standard function. Instead, they might offer support in the form of advice or guidance and may collaborate with external legal professionals when necessary.

The other functions listed align closely with the core responsibilities of trade unions. Campaigning for better working conditions is fundamental to what unions do, as they seek to improve the overall environment for their members. Protecting members’ interests is a very central aspect of union activities, ensuring that the voice of the workforce is heard. Additionally, representing employees in disputes is a critical role, as unions act on behalf of members during disagreements with employers, striving for fair resolutions. Therefore, the task of providing legal representation does not fall within the standard functions of trade unions.
