Final answer:
In NH, employers must complete an Employment Certificate and a Job Information Sheet before hiring a youth to comply with state labor laws and ensure the work is appropriate for minors.
Step-by-step explanation:
Before hiring a youth in the state of New Hampshire (NH), an employer must ensure that two important documents are completed. These are the Employment Certificate, also known as "working papers," which provides information about the minor and certifies their eligibility to work under state labor laws, and a Job Information Sheet or equivalent, detailing the nature of the youth's employment. This process helps to ensure that the work is suitable and does not interfere with the youth's education or health.
