I didn’t know that, I’m a fairly recent import from FL, but they had really lax child labor laws there too. When I was a minor my managers at two different companies regularly broke break schedule laws even though I would remind them I had to take an unpaid break every 4 hours, I’d hit overtime and work overnights at one job because I didn’t have a traditional school schedule and could work different hours. At 16/17 years old. But it’s a little different than 10 year olds hitting the mines, hopefully it never goes to that again at least.

NHPR had an article about it because bosses were pressuring them to work during school.
