Question

Quizplus · Accepted Answer

When unions raise wages in some sectors, workers are attracted to these higher-paying jobs, reducing the supply of labor in non-unionized sectors. This increased supply of labor in the unionized sector can lead to a decrease in wages in the non-unionized sectors due to the excess supply of labor there.
