Those "some conditions" being:
Not on school days.
Not on sundays, except if you didn't work Saturday and only a dozen per year.
No factory or machine work
No dangerous materials
No register work
No loading/unloading
No delivery work
No late or night work
No loud noises
I feel Russia doesn't quite hold to the same list of requirements.
Stuff like stocking shelves at the supermarket, helping around your parents work.
But yeah, the list is intentionally short.
