I think the best thing to do would be to strike the "including education" part and then lower the hours a bit to keep the spirit of the clause. 30 hours? more/less?
In NY they divide it into categories for 14/15 year olds and 16/17 year olds and theres different hours that students can work on school days, on non-school days, and when school isn't in session like during the summer break. They have it at 28 hours for 16/17 year olds and 18 hours for 14/15 year olds. Not saying that's the best way, but it's an example. I think we should consider lowering the minimum age to 15 or maybe 14 too.
Here's the website where I got the info for NY. It has a handy chart at the bottom.
