The closest I come to working with part-time, minimum-wage workers is working with student employees. Even then, they earn more and usually work more than five hours a week.

Most of the time, I end up putting in more work than I get out of it. Onboarding, reviewing, and mentoring all take significant time.

Even with the best students we had, paying around 400 euros a month, I would not say that I saved five hours a week.

And even when they reach the point of being truly productive, they are usually already finished with their studies. If we then hire them full-time, they cost significantly more.
