In the 1990s, the wide dissemination of technological innovations, changes in models of production and the organization of work and the extension of the process of European integration led social stakeholders to adapt the national systems of collective bargaining and to anticipate the effects of the introduction of the Euro. In so doing, they opened the way for a certain number of institutional reforms. Several movements took place in parallel: a marked slowdown in wage increases, inter-professional summit agreements that gave the signal for decentralisation of negotiations, improved articulation between branches and enterprises, multi-dimensional bargaining, and the increasingly important part played by the variable components of remuneration. In this context, the weight of the branches in wage negotiations has diminished, and that of enterprise, directly subject to international competition and the process of European integration, has increased.
