How many hours can a 16/17-year-old legally work in a school day?

For 16 and 17-year-olds, the legal working hours in a school day are set to ensure that their education is not adversely affected by their employment. The correct answer states that they can work 3.5 hours on a school day. This duration is designed to balance the responsibilities of school and work while protecting young workers' rights and ensuring they have sufficient time for their academic commitments.

It is important to note that specific labor laws may vary by jurisdiction, but many regulations recognize the need for students to prioritize their education. By limiting working hours on school days to 3.5 hours, it supports the importance of their schooling while still allowing some work experience.
