Final answer:
It is true that unions and some governments believe collective bargaining has significant limitations against MNCs due to globalization and the power of MNCs to move operations.
Step-by-step explanation:
Unions, as well as some governments, have asserted that collective bargaining on a national basis has considerable limitations in facing Multinational Corporations (MNCs). This assertion is true. Collective bargaining is a process where labor unions negotiate with employers to establish the terms and conditions of employment. However, the scale and power of MNCs, who can shift production to countries with cheaper labor costs and lower regulatory standards, can weaken the negotiating power of unions operating solely within national borders.
American union membership has declined over the decades due to factors like global competition and the passage of worker-friendly legislation. Moreover, labor unions have historically faced challenges such as businesses lobbying against collective bargaining, arguing for individual contract freedom, which was more about reducing the collective power of unions than championing worker liberties.
Globalization has indeed shaped union dynamics, and collective bargaining on a national level may not adequately address the global strategies employed by MNCs, thus creating limitations for national unions in protecting workers' interests against MNC practices.
