Citizens` trust in trade unions also varies greatly from country to country (data on trust in employers` organisations are not available) and are correlated with the national level of trust in institutions in general. In 2010, on average, 40% of respondents in OECD countries reported being unionised, but the proportion of people who trust trade unions varies between 65% in Finland and Denmark and 25% in the United States, Slovenia and Mexico. Between 2000 and 2010, trust in trade unions in the countries of Central and Eastern Europe, where it was initially very low, increased markedly, while it decreased considerably in the crisis-affected countries of Greece, Ireland and Spain. ← 33. Due to opposition from trade unions to full decentralisation and employers` organisations (dominated by large companies), they have resisted increased competition in wage fixing. And also because of the lack of capacity and representation of workers to negotiate agreements at company level. However, in two-thirds of the countries shown in Table 2.7 (Panel B), younger workers seem less convinced that older workers need strong unions to protect their interests. The result is a surprising pattern in countries such as Denmark, France, Latvia, Lithuania, Slovenia or Sweden, where young respondents have more confidence in trade unions than older people, but are less convinced that workers need it to protect their rights. The explanation of these contradictory models would go beyond the scope of this box. However, these data do not support strong claims about the low interest of young workers in taking collective measures that are at the root of the age-related difference in affiliation. The overall impact of collective bargaining on economic performance depends largely on the specific characteristics of each country`s system, how they interact with other key parameters of labour market institutions, such as job protection or minimum wage legislation, but also on prevailing macroeconomic and labour market conditions and policies. .
