Notes: (a) – a limited number of provisions are extended; (b) many agreements that are subject to an extension do not contain provisions on wages or salary levels. In France, almost all workers are covered by inter-professional agreements, but they often offer only minimum conditions, with improvements negotiated at the company level or individually with employees. The inadequate tariff measures the relative importance of the collective agreement as a regulatory mechanism in a given country. The appropriate rate indicates the “governance capacity” of a collective agreement within its own domain. In order to arrive at a valid cross-border comparison of wage setting, it is important to distinguish between the two variants, as countries differ in that workers are excluded from the right to negotiate. In Sweden, the collective agreement was 90% in 2017 (83% in the private sector, 100% in the public sector).   In 2017, union density was 69% (64% in the private sector, 79% in the public sector). In Greece, a number of legislative changes in 2011 and 2012, including the admission of enterprise-level agreements, branch-level agreements, the limitation of the validity of expired contracts and the government`s removal from large-scale agreements, have led to the collective agreement being increased from about 65% of employees before the crisis to 10% at present. An enterprise agreement may also apply to the employment of a worker by an employer in some circumstances, but not in others (for example. B if the agreement is specific to the location and if the employee`s workplace changes). The question of when the agreement will be implemented is determined by the scope and conditions of coverage of the agreement itself.
 For all these reasons, the data reported here are not necessarily comparable to previous series of other studies for the period 1980-1996 (see Traxler et al 2001 above), which were capable of: In addition, The Committee on the Environment, Health and Health policy and economic affairs and personal health and safety policy (OECD) was tasked with verifying the data for Spain and Norway, as well as providing data on uncorrected and adjusted data for more countries in the european and non-European Organisation for Economic Co-operation and Development (OECD) field. In Sweden and Denmark, most workers are involved in the sector`s activities, but the lower negotiators have considerable leeway. In Sweden, only 10% of all employees had fully set their wages through sectoral collective agreements during the 2013 collective bargaining, while in Denmark, in the largest group of agreements that covered 85% of LO trade union employees in the private sector, wages are set by local enterprise-level agreements.
