Correct Option: A Explanation of Why Option A is Correct The principle of collective bargaining is fundamentally based on the idea that employees can achieve better negotiation outcomes when they come together as a group, typically through a union. This collective strength allows them to negotiate terms of employment, wages, and working conditions more effectively than they could as individuals. Option A states: "individual employees have weak bargaining base." This statement negates the principle of collective bargaining because it emphasizes the inherent weakness of individual employees in negotiations. If individual employees are indeed weak in their bargaining position, it underscores the necessity of collective bargaining, which is designed to empower them by pooling their resources and voices. Therefore, this option directly contradicts the essence of collective bargaining, which is to strengthen the bargaining power of employees through unity. Why the Other Options are Weaker or Incorrect Option B: "individual employees attain strength when they come together in union." This statement supports the principle of collective bargaining rather than negating it. It highlights the core idea that unity among employees enhances their bargaining power. Therefore, this option is incorrect in the context of the question. Option C: "only members of the union can benefit from agreements negotiated by the union." While this statement is true in many contexts, it does not negate the principle of collective bargaining itself. Instead, it reflects a characteristic of union agreements. The principle of collective bargaining still applies to the process of negotiation, regardless of who benefits from the outcomes. Thus, this option does not contradict the principle. Option D: "collective bargaining covers the vast majority of employees, whether union members or not." This statement also supports the principle of collective bargaining. It suggests that collective bargaining has a broad impact, extending beyond just union members. This indicates that collective bargaining is a significant mechanism in labor relations, further reinforcing its importance rather than negating it. Summary of Key Points
