Missouri has specific labor laws that regulate the employment of minors. These laws are in place to ensure that young workers are protected from hazardous conditions while also allowing them to gain valuable work experience. Understanding Missouri’s legal working age, the requirements for work permits, and the restrictions on certain jobs is essential for both employers and young job seekers.
Minimum Working Age in Missouri
In Missouri, the minimum legal working age is 14 years old. However, there are exceptions for younger children in certain occupations. For example, children under 14 may work in entertainment (such as acting or modeling) and certain family-owned businesses, provided the work does not interfere with their education or well-being. Babysitting, newspaper delivery, and casual yard work are also exempt from these regulations.
Work Permit Requirements for Minors
Minors under 16 years old are required to obtain a work permit before they can be legally employed. Work permits ensure that the employment does not interfere with their education and that the job is safe for their age group. The process for obtaining a work permit in Missouri includes:
- Obtaining Permission – The minor must secure written consent from a parent or guardian.
- School Approval – The minor’s school must verify that their academic performance and attendance are satisfactory.
- Employer Details – The employer must provide a job description, detailing the nature of the work and hours involved.
- Issuance of Permit – The work permit is issued by the school district superintendent or an authorized school official.
For minors aged 16 and 17, work permits are generally not required, though certain job restrictions still apply.

Missouri labor laws prohibit minors from working in certain hazardous occupations. The restrictions vary based on age, with stricter limitations for those under 16. The following are some of the prohibited jobs for minors:

Exemptions and Special Work Situations
Some minors may qualify for exemptions from these labor restrictions, including:

- Ensuring minors obtain the necessary work permits
- Adhering to job restrictions and prohibited occupations
- Monitoring and enforcing hour limitations
- Maintaining proper records of minor employees and their work schedules
- Providing a safe working environment free from hazardous conditions
Consequences of Violating Child Labor Laws
Employers who violate Missouri’s child labor laws may face serious penalties, including:
- Fines and legal penalties imposed by the Missouri Department of Labor
- Revocation of business licenses in severe cases
- Lawsuits from employees or their families in cases of injury or exploitation
- Potential federal penalties if violations also breach federal child labor laws
Conclusion
Missouri’s child labor laws aim to protect minors from unsafe working conditions while allowing them to gain experience in the workforce. While minors aged 14 and older can work legally with some restrictions, they must obtain a work permit and adhere to job and hour limitations. Employers must also follow regulations to ensure compliance and avoid legal consequences. By understanding these rules, young workers, parents, and businesses can work together to create safe and beneficial employment opportunities for minors in Missouri.
