Vereinigungsfreiheit
Freedom of association is the foundation of the collective-bargaining process. Before a group or collective may engage in collective bargaining, it is necessary that legal protection be extended to that group or collective. Legal measures are also necessary to protect the rights of people to belong to a group or collective. This is what freedom of association is all about: the legal protection of the freedom of persons to join a collective entity. The law, therefore, both permits people to join trade unions, and also protects their right to do so.
