In 24 states, workers working in a unionized company may be required to participate in representation fees (for example. B for disciplinary hearings) if their colleagues negotiated a union security clause in their contract with management. The fee is usually 1 to 2% of the salary. However, union members and other employees receive on average a wage increase of 5 to 10% compared to their non-unionized (or unsured) colleagues.  Some states, particularly in the southern parts of the central and southeastern United States, have banned union security clauses; This can be controversial because it allows some net beneficiaries of the union contract to avoid paying their share of the cost of contract negotiations. Regardless of the state, the Supreme Court ruled that the law prevented a person`s trade union rights from being used without consent to fund political concerns that might conflict with the individual`s personal policy. Instead, in states where union security clauses are permitted, these deviants can only pay the share of levies paid directly to the representation of workers.  A collective agreement is the agreement between the employer and the union that governs the employment of workers who are members of that union. It is important that the agreement be reached between the union and the employer, not between the employer and its individual workers. In Sweden, the scope of collective agreements is very high, although there are no legal mechanisms to extend agreements to entire industrial sectors. In 2018, 83% of all private sector employees were subject to collective agreements, 100% of public sector employees and 90% in total (compared to the overall labour market).  This reflects the predominance of self-regulation (regulation by the labour market parties themselves) over state regulation in Swedish industrial relations.
 The right to collective bargaining is recognized by international human rights conventions. Article 23 of the Universal Declaration of Human Rights describes the ability to organize fundamental human rights unions.  Point 2 (a) of the International Labour Organization`s statement on fundamental principles and rights in the workplace defines “freedom of association and effective recognition of the right to collective bargaining” as an essential worker`s right.  The 1948 Convention on Freedom of Association and the Protection of the Right to Organization (C087) and several other conventions protect collective bargaining in particular by creating international labour standards that deter countries from violating workers` right to co-association and collective bargaining.  Other collective agreements provide for rules on the relationship between the employer and individual workers.
