The government is subject to the Freedom of Information and Protection of Privacy Act with respect to the provision of agreements containing personal data such as employee names. This information is blacked out before the agreement is made available for research. The definition of a collective agreement is contained in the Participation Act, which stipulates that a collective agreement is a written agreement between employers` organizations or an employer, on the one hand, and a workers` organization, on the other, which governs the conditions of employment or relations between employers and employees. An agreement is considered written if its contents have been recorded in approved protocols or if a contract proposal and acceptance have been recorded in separate documents. Oral agreements or agreements which do not concern relations between employers and employees are not considered to be a collective agreement. Workers are not required to join a union on a given job. However, most sectors of activity with an average trade union organization of 70% are subject to a collective agreement. An agreement does not prohibit higher wages and better social benefits, but sets a legal minimum, much like a minimum wage. In addition, a national agreement on income policy is often, but not always, reached, including all trade unions, employers` organisations and the Finnish government.  How long will it take after a treaty is ratified for the parties to develop and sign the new collective agreement? In Sweden, the coverage of collective agreements is very high, although there are no legal mechanisms to extend agreements to entire sectors. In 2018, 83% of all private sector employees were covered by collective agreements, 100% of public sector employees and 90% in total (across the labour market).
 This reflects the predominance of self-regulation (regulation by the labour market parties themselves) over government regulation in Swedish industrial relations.  Collective agreements are concluded for certain periods, generally between two and four years. A collective agreement is binding both for the employers` organisation and its members, on the one hand, and for the trade union and its members, on the other. In addition, in practice, if not theoretically, a collective agreement binds non-unionized and unionized workers belonging to unions other than the union that is part of the agreement, provided that (i) the worker works with tasks covered by the contract and (ii) the union to which the worker belongs, he is not bound by another collective agreement with the employer. . . .
