One of the challenges of free movement of labour within the SEM is?

The challenge of increased competition for jobs is a significant issue in the context of the Single European Market (SEM) and the free movement of labor. When labor can move freely across borders, workers from different member states can apply for the same positions, leading to a greater number of candidates for each job opening. This influx can intensify the competition among applicants, as local job seekers must now contend with a potentially larger pool of qualified individuals from other countries.

In this environment, employers may benefit from a larger selection of candidates, which might allow them to hire individuals with a wider range of skills or at lower costs, depending on the local labor market conditions. However, this increased competition can also pose challenges for local workers, who may find it harder to secure employment due to the higher number of applicants.

This context is important for understanding the dynamics of labor movement within the SEM, as it directly affects job availability and stability for domestic workers. The other options do not specifically capture this aspect of competition that arises when labor markets become more integrated and open.
