How were unskilled workers characterized in terms of job security?

Unskilled workers are characterized as easy to replace due to the nature of their work, which typically requires minimal training or specialized skill sets. Many unskilled positions, such as those in manual labor or entry-level service jobs, can often be filled quickly from a larger pool of available workers. This high availability is driven by factors like lower barriers to entry into these jobs and a steady influx of individuals seeking employment. Consequently, employers may not feel the need to offer job security or significant benefits, as the workforce can readily replenish itself.

This context highlights why this characterization of unskilled labor is prominent in discussions about job stability and worker rights, often leading to increased vulnerability for unskilled workers in economic downturns or shifts in demand. In contrast, the other options suggest qualities that unskilled workers typically do not possess, such as being difficult to replace or well-trained, highlighting the unique challenges faced in these roles.
