Multinational corporations operating in Great Britain, specifically American industry, are arousing fears on the part of British labor, which can be grouped into these categories: (1) a threat to the job security of union members, (2) a change in the balance of power at the collective bargaining table in favor of the employers, (3) a clash of interests between the goals of international industry and the aims of the British government, which may be resolved against the interests of labor, (4) possible refusal to recognize or negotiate with British labor unions, and (5) difficulties in locating the decision-making source. Anxiety about the introduction of industrial relations practices alien to Great Britain was alleviated by these successful innovations by foreign multinational companies: (1) the development of productivity bargaining, (2) fixed term company agreements, (3) financial incentives to observe agreed procedural arrangements, and (4) the introduction of single status plants. Although short-term British union policies may aim for controls over international companies, long-term union policies will probably favor multinational trade unionism. (Author/AG)
