OECD/AIAS ICTWSS database

 

How do collective bargaining systems and workers’ voice arrangements compare
across OECD and EU countries?

 

In all OECD countries, workers and employers associate to express their interests and concerns and to negotiate the terms and conditions of employment. However, national systems of collective bargaining display very significant differences, which, in part, are related to different regulations and, in part, to different practices and traditions.

The OECD/AIAS database on Institutional Characteristics of Trade Unions, Wage Setting, State Intervention and Social Pacts (ICTWSS) provides comprehensive and comparable information on the evolving nature and scope of collective bargaining in OECD and EU countries. The database was initially developed by Prof. Jelle Visser at the University of Amsterdam (AIAS-HSI) and, in 2021, it has been rebranded as the OECD/AIAS ICTWSS database. This new name reflects the joint effort by the OECD and AIAS-HSI to ensure the continuation of the database after Prof. Visser’s retirement.

How does collective bargaining work in your country? The profiles below provide a snapshot of the key elements characterising the functioning of collective bargaining. The profiles use a consistent format and wording to facilitate comparisons across countries and therefore do not describe in full details the exact regulation in each country.
