I would think of it as 'take your kids to work', but more often. I am not a big fan. I was coming to my dad's car shop after school and I can't honestly say that I learned anything useful ( I could have, but did not ).
My mom was single and poor so I also got to spend from 3pm to 7pm most evenings sitting in her classroom, which for some years was an actual server closet, desperately trying to note die of boredom while my mother had meetings and graded papers.
This was so useful, important, and necessary for my future /s
I think these were called apprenticeships at one time
What if you have some soul-crushing dead-end office job? How long do you think a 6-year-old would last in an airline customer support call center?
In this case, he had a certain amount of records to print in the time allotted, and he needed two operators to make the window. I learned a lot of useless knowledge about which medical procedures qualify for extra reimbursement for Medicare, and also what Sunset Park, Queens looked like at 3am. Nothing really useful in life.
I think if my dad had hired someone and let me sleep and play on the computer instead, that probably would have turned out better for me.
