Focusing on employers’ organizations in the United Kingdom, this article contributes to the literature on employer interest representation by advancing three interrelated arguments, which reflect how the methods, structure and interests of employer representation have evolved. First, the primary method of collective interest representation has shifted from collective bargaining, nowadays only pursued by a minority of employers’ organizations, to political representation, now the most frequent form of collective interest representation. Second, the structure of employer interest representation has evolved and is fragmented between a small number of large, general employers’ organizations, a large majority of sectoral employers’ organizations, regional interest representation in the devolved nations, which has become more important, and a new type of employer body, the employer forum, which focuses on corporate social responsibility. Third, the shift in collective interest representation is complemented by a broadening of individual interest representation, with employers’ organizations having developed a wide range of services.
