The Office of Labor-Management Standards, part of the U.S. Department of Labor, is required to collect all collective agreements for 1,000 or more workers, except those for railroads and airlines.  They provide public access to these collections through their website. In Sweden, around 90% of employees are covered by collective agreements and 83% in the private sector (2017).   Collective agreements generally contain minimum wage provisions. Sweden has no legislation on minimum wages or laws to extend collective agreements to disorganized employers. Unorganized employers can sign replacement agreements directly with unions, but many are not. The Swedish model of self-regulation applies only to companies and workers covered by collective agreements.  The Act is now included in the Trade Union and Labour Relations (Consolidation) Act 1992, 1992, 179, which provides that collective agreements are not legally binding in the United Kingdom.
This presumption can be rebutted if the agreement is in writing and contains an explicit provision stating that it should be legally enforceable. In the United States, the National Labor Relations Act (1935) covers most collective agreements in the private sector. The Act makes it illegal for employers to discriminate, spy, harass or terminate workers because of their union membership, or to retaliate against them because they participate in campaigns or other « concerted activities », form company unions or refuse to negotiate collective agreements with the union representing their employees. It is also illegal to require any employee to join a union as a condition of employment.  Trade unions are also able to guarantee safe working conditions and fair remuneration for their work. In Finland, collective agreements are universal. This means that a collective agreement in a sector of activity becomes a universal legal minimum for everyone`s employment contract, whether or not they are unionized. .
