What's everyone's opinions on letting minors above a certain age do some part-time labor?

I used to do odd jobs around my neighborhood as a teen and I actually kind of liked it, I got walking around money and the work was actually kind of fun and was maybe even a bit educational and enriching. I mean I guess this is also sort of the role Scouting/Pioneer organizations filled in society, since a lot of it is getting kids to do some free charity labor but it's for like nice stuff like cleaning up the park and not working in a factory.

IDK about having kids bag groceries and or be cashiers and shit. I think that's basically just a way for retail businesses to cheap out on labor.
