Some collective agreements refer to the general relationship between an employer or employer organisation and trade unions. These agreements generally address issues such as participation, negotiation procedures and the definition of common objectives related to future labour market developments and employers. Agreements are generally reached between federal employers` organizations and their central union counterparts at the federal level with the above themes. If collective bargaining has resulted in an agreement, such as wage increases, these agreements are called collective agreements. Workplace collective agreements can cover both union and non-union staff, as unions often negotiate on behalf of staff employed in a particular group. This group is called the bargaining unit. It is important to note that after the conclusion of a KBA, both the employer and the union are required to respect this agreement. Therefore, an employer should retain the assistance of a lawyer before participating in collective bargaining. In Sweden, about 90% of employees are subject to collective agreements and 83% in the private sector (2017).   Collective agreements generally contain minimum wage provisions. Sweden does not have legislation on minimum wages or legislation extending collective agreements to disorganised employers. Unseated employers can sign replacement agreements directly with unions, but many do not. The Swedish model of self-regulation applies only to jobs and workers covered by collective agreements.
 One of the advantages for workers when setting up and joining a union is the strengthening of their negotiations against their employers. A worker is unlikely to be able to get his or her employer to agree on new safety measures or higher wages, but more workers will have a better chance. This is an example of collective bargaining. In the United States, about three-quarters of private sector employees and two-thirds of public sector employees are entitled to collective bargaining. This right came to American workers through a series of laws. In 1926, the Railway Labour Act granted railway workers collective bargaining and now covers many transport workers. B, for example in airlines. In 1935, the National Labor Relations Act clarified the bargaining rights of most other private sector employees and established collective bargaining such as “U.S.
policy.” The right to collective bargaining is also recognized by international human rights conventions. Every year, millions of American workers negotiate or renegotiate their negotiated contracts. However, some employers are trying to undermine existing bargaining relationships and reduce many harsh contractual terms. Unions continue to fight for the intrinsic rights of workers and restore the balance of our country`s economic power through collective agreements. Other collective agreements contain rules on the relationship between the employer and individual workers. Such agreements can be concluded at the central level, by the parties described above and at the local level, between a specific employer and the local union represented in the company. It is customary for a central agreement on the conditions of employment of each worker to be supplemented by local agreements. This is the standard procedure among companies that are members of the Swedish Association of Industrial Employers.
