What term describes individuals hired as trainees in occupations that are non-apprenticeable?

The term that describes individuals hired as trainees in occupations that are non-apprenticeable is "learners." This designation encompasses individuals who are actively engaged in acquiring skills and knowledge within a specific field or job, but the role does not involve the structured, formal apprenticeship model seen in trades.

Learners are typically placed in roles where they can develop their capabilities through practice, on-the-job training, or mentorship without the formalities and requirements that come with apprenticeship programs. Unlike apprentices, who are often engaged in skilled trades with a defined structure and certification process, learners may find themselves in a variety of settings across different industries where formal apprenticeship isn't applicable.

The other terms such as interns, students, and apprentices have specific connotations and sometimes structured programs that do not align with the broader and less formal training context that learners represent. Interns often work in temporary positions to gain practical experience and may still require an educational component; students are primarily enrolled in educational programs without direct employment connotations; and apprentices are involved in specific training programs leading to certification in skilled trades.
