Final answer:
Minimum-wage workers are often young, less educated, and employed in industries such as food service. However, the incorrect characteristic for minimum-wage workers is that they are primarily full-time workers, as many hold part-time or seasonal positions.
Step-by-step explanation:
When considering the characteristics of minimum-wage workers, it is important to understand the demographic and employment traits that commonly define this group. Minimum-wage workers tend to be concentrated in industries such as food service and drinking places, with many being less educated, such as those lacking a high school diploma. They also tend to be younger, which often correlates with lower levels of experience and education, making it challenging to secure higher-paying jobs.
However, a common misconception is that minimum-wage workers are primarily full-time employees. This is not the case; many minimum-wage jobs are part-time or seasonal. For instance, a construction worker who is laid off might take a temporary job at a fast food restaurant, although it's not their preferred or permanent line of work. The working poor also tend to have jobs without benefits and are often in temporary or seasonal positions.
Therefore, the characteristic of minimum-wage workers that is not accurate is (d) full-time workers. While some minimum-wage workers do work full-time hours, a significant proportion do not, and therefore, this cannot be considered a defining characteristic of the group.
