Unions limit the operation of:

A. democracy
B. the justice system

D. the military

None of the above.

That's my opinion.

What does your book say?

Unions generally do not limit the operation of democracy, the justice system, or the military. However, they can have an impact on market forces.

To answer this question, let's break it down and examine each option individually:

A. Unions and Democracy: Unions may actually be seen as supportive of democracy. They represent workers' interests and provide a platform for collective bargaining, allowing workers to have a voice in workplace decisions. Unions advocate for fair wages, better working conditions, and workers' rights. So, unions do not limit the operation of democracy.

B. Unions and the Justice System: Unions and the justice system are separate entities with different roles. Unions may engage legal assistance and take legal action if they believe their rights are violated. However, this does not limit the operation of the justice system itself.

C. Unions and Market Forces: Market forces refer to the principles of supply and demand that influence the economy. Unions can impact market forces by negotiating wages and benefits with employers. This can lead to increased labor costs for businesses, potentially affecting prices, productivity, and competitiveness. So, unions can have some influence on market forces.

D. Unions and the Military: Unions have limited involvement in the military. In many countries, individuals serving in the military are generally not allowed to form or join unions due to the unique nature of military service and the need for a hierarchical command structure. Therefore, unions do not have a significant impact on the military's operation.

In summary, unions do not limit the operation of democracy, the justice system, or the military. However, they can have an impact on market forces, specifically in relation to labor costs and negotiations between workers and employers. Therefore, the correct answer is C. market forces.
