Bargaining in the Nordics is more inclusive than in the average OECD country, with high shares of organised workers (Figure 8) and firms, and high coverage of collective agreements (OECD 2017c). This also contributes to trust, together with long-standing cooperation, peace clauses, effective mediation and a high level of firm-level worker representation. Unionisation has steadily declined in the OECD since the 1980s. This is also the case in the Nordics (except for Iceland), but membership is still very high compared to other countries.
