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.  Workers are not required to join a union in a specific workplace. Nevertheless, most industries, with an average union training of 70%, are subject to a collective agreement. An agreement does not prohibit higher wages and better benefits, but sets a legal minimum, much like a minimum wage. In addition, an agreement on national income policy is often, but not always, reached, bringing together all trade unions, employers` organisations and the Finnish government.
 The labour code requires unions and employers to file a copy of their collective agreement with the Director of Mediation Services. Section 150.1 of the Labour Code requires collective agreements to be filed within 30 days of the contract being concluded. The authors note that 98 per cent of collective agreements contain wage clauses, but few agreements indicate the level of wages. Up to 71% have social security clauses, 89% of working time and 84% of family employment contracts. The authors also note that collective agreements, including one of these four clauses, are more likely to include the other three and conclude that there is no trade-off between their inclusion on the negotiating agenda. The province uses this data to produce reports such as the updated negotiations, which provide labour relations and tariff information to the public. For more than three years, WageIndicator, in collaboration with the University of Dar es Salaam, has been creating a Global Collective Agreements (CBAs) database to inform workers of rights they seem to be unaware of. The database also allows them to know what is happening in other sectors of their country and in other countries.
This can be done by comparing CBA clauses between different topics such as maternity leave, working time, social security, days off, annual leave, minimum wages, etc. We believe that this can increase workers` bargaining power when new conditions are discussed with the employer or when negotiations are conducted to improve existing conditions and create new ways to improve their working conditions.
