Tripartism refers to economic corporatism based on tripartite contracts of business, labour, and state affiliations within the economy. Each is to act as a social partner to create economic policy through cooperation, consultation, negotiation, and compromise. Tripartism is a common form in neo-corporatism.
Tripartism became a popular form of economic policy during the economic crisis of the 1930s. Tripartism was supported from a number of different political perspectives at this time: one was Catholic social teaching; fascism supported this for fascist unions but repressed communist and social democratic unions; and in democratic politics. Tripartism is a prominent economic policy in Europe, particularly where Christian Democratic parties influenced by Catholic social teaching have held power; it is a core part of the economic systems in Scandinavia and the Benelux that were put in place by social democratic governments. An example is a national income policy agreement in Finland. Tripartite agreements are an important component in practical labour law, since they cover not only wages, but also issues such as policies on benefits, vacation, workhours and worker safety.
