Final answer:
Workers not employed full-time may take part-time or temporary roles, and they often fall into the hidden unemployment category, which includes underemployed and discouraged workers not actively seeking employment.
Step-by-step explanation:
Part-time or temporary positions are often used by workers who are not employed on a full-time basis by the company.
These individuals can be a part of the hidden unemployment category, which includes those who are employed less than they desire, such as part-time workers seeking full-time work and individuals who are underemployed in positions that don't utilize their skills or provide adequate compensation.
Discouraged workers, who have stopped looking for jobs because they believe none are available, also contribute to hidden unemployment despite being out of the active labor force. Examples include someone who opts for a part-time job due to the lack of full-time opportunities, or a college student engaged in an unpaid internship.
