What best describes unemployed workers?

The correct choice describes unemployed workers as those who are out of work but actively seeking work. This definition aligns with the standard economic and labor market criteria for unemployment, which considers individuals who do not have a job but are actively looking for employment opportunities. It emphasizes that merely being out of work does not categorize someone as unemployed; their active job search is a crucial component.

The other choices do not fit this definition. Individuals who are not looking for a job would not be considered unemployed, as they do not meet the criteria of actively seeking employment. Those who are employed part-time have jobs, therefore they are not classified as unemployed. Lastly, retired individuals have left the workforce and do not seek employment, which also disqualifies them from being considered unemployed.
