The main purpose of this legislation is to amend the Fair Labor Standards Act of 1938 to allow teenagers aged 14 to 16 to work more hours during the school year. The goal is to provide young people with opportunities to gain work experience and develop necessary skills while still attending school. Key provisions of the legislation include allowing these teenagers to work up to 24 hours a week when school is in session. It specifies that they can start work no earlier than 7:00 a.m. and must finish by 9:00 p.m.
