Final answer:
People who are temporarily absent from their job and people who work without pay in a family member's business are considered 'out of the labor force'.
Step-by-step explanation:
In the context of labor force classification, people who are temporarily absent from their job and people who work without pay in a family member's business are considered out of the labor force. This category includes individuals who are not actively seeking employment or are unavailable to work due to various reasons such as vacation, illness, childcare responsibilities, or parental leave.
It is important to distinguish these individuals from the unemployed, who are actively seeking employment but currently without a job. Additionally, there are cases of hidden unemployment, where individuals are employed but either underemployed or have temporary positions when they prefer full-time and permanent employment.
