Correct Option: C Explanation of Why Option C is Correct: The principle of collective bargaining is fundamentally about the negotiation process between employers and a group of employees, typically represented by a union. This process aims to establish terms of employment, such as wages, working conditions, and benefits, that are beneficial to the collective group of employees. Option C states: "only members of the union can benefit from agreements negotiated by the union." This statement negates the principle of collective bargaining because it implies exclusivity. If only union members benefit from the agreements, it undermines the collective nature of bargaining, which is designed to represent and protect the interests of all employees, not just those who are union members. This exclusivity can lead to division among employees and weaken the overall bargaining power of the group, as it creates a scenario where non-union members may feel disenfranchised and less likely to support collective efforts. Why the Other Options Are Wrong or Weaker: Option A: "individual employees have weak bargaining base." - This statement is true in the context of individual negotiations; however, it does not negate the principle of collective bargaining. In fact, it supports the need for collective bargaining because it highlights the strength that comes from employees banding together. Therefore, this option does not contradict the essence of collective bargaining. Option B: "individual employees attain strength when they come together in union." - This option is also true and reinforces the principle of collective bargaining. It emphasizes that collective action enhances the bargaining power of employees, which is the very foundation of why unions exist. Thus, this option does not negate collective bargaining; rather, it supports it. Option D: "collective bargaining covers the vast majority of employees, whether union members or not." - This statement is generally accurate and reflects the inclusive nature of collective bargaining. It suggests that even non-union members can benefit from the agreements reached through collective bargaining, which is contrary to the idea of exclusivity presented in Option C. Therefore, this option does not negate collective bargaining; it highlights its broader impact. Summary of Key Points:

• Collective Bargaining: A process where employees negotiate as a group with their employer to establish fair terms of employment.
• Correct Answer (C): Exclusivity in benefits for union members undermines the collective nature of bargaining.
• Supporting Options (A, B, D): These options highlight the importance of collective strength and the inclusive nature of collective bargaining, reinforcing rather than negating the principle.
• Importance of Unity: Collective bargaining is most effective when all employees, regardless of union membership, support the negotiations to strengthen their position.

This understanding of collective bargaining is crucial for students preparing for exams in commerce, as it highlights the dynamics of labor relations and the importance of unity among employees.
