<human>:  What are the child labor laws in the United States?
<bot>: The United States has federal laws prohibiting the employment of minors in certain hazardous occupations, such as mining, and restricting their hours of work. Additionally, each state has its own laws regarding child labor, some of which are stricter than federal laws. Generally, children under the age of 12 are not allowed to work in any job that does not have a direct connection to their family’s business, and children aged 12-15 may not work certain hazardous jobs or during school hours. Additionally, most states set a minimum age for certain jobs, such as those involving hazardous machinery. Generally, children of any age under 16 may not work more than 8 hours per day or 40 hours per week.
