Bargaining collectively instead of acting only individually.
Working hours, pay and other conditions often affect many employees at once. Unions combine their interests and can negotiate collective agreements with employers. This differs from running a business.
Article 9(3) protects associations safeguarding and improving working and economic conditions. This right provides a foundation for unions and employers’ associations. It does not make the two sides the same organisation.
The other three answers
Focus on the role in the employment relationship.
large companies
Large companies belong to the employer side. Having many employees does not make unions the companies’ representatives.
small companies
Small companies are likewise not employee representatives simply because they are small. The distinction concerns employer and employee interests, not business size.
self-employed
Self-employed people are not the general main group intended by this catalogue question. However, the option should not be read as excluding every self-employed person: ver.di, for example, also organises solo self-employed workers.
The catalogue answer describes the core role, not every membership.
Union organisation is more varied than the four short options suggest. Some self-employed workers being organised does not change the intended basic concept of employee representation. It does rule out the false extra claim that self-employed people can never belong.
A trade union is not the same as company management. Negotiating conditions and representing interests does not automatically make it responsible for running the workplace or hiring its staff.
Article 9(3) · Basic Law ↗Trade union → workers’ side. Employers’ association → employers’ side.
Learn which interests are represented, rather than company size. Employees are the appropriate group in this question.
