Answer:
C. The trade off between wages and employment faced by the union.
Step-by-step explanation:
The Union basically negotiates the pay a union worker will receive from the firm or organization. Unions use several techniques to increase the demand for labor and wages as well.
- They push for minimum wage increase.
- Increase the marginal productivity of workers.
- Lobbying for stricter immigration rules. This limits growth in the labor supply, especially of low-skilled workers from outside the country.
- They support restrictions on imported goods. This increases the demand for domestic production and domestic labor.
