3. Mobility is of course not absolute. Moving existing operations abroad is not necessarily easy, as firms have sunk costs in their existing locations, i.e. investments in installations, distribution, supplier networks, social relations, etc. (Crouch in this issue). Also, the most advantageous location is not necessarily the one with the lowest costs or the weakest regulations and industrial relations systems, as the attractiveness of the high-wage, high-tax, high union-density Nordic countries for capital shows (ibid.) borders, and collective bargaining processes, taking place, if at all, within national borders at the level of company or sector. Although there are a number of international trade union organizations, in which national confederations or sectoral unions join forces (see below), they have few resources compared to capital and only in a very limited number of cases are they collective bargaining actors. As a result, trade unions or other workers’ representatives have little or no control over or influence on issues addressed at the international level and international decision-making is largely monopolized by company management (van der Meer et al., 2004).
