Missouri Child Labor Law

Last update: June 10, 2023

Minimum Hiring Age in Missouri

What is the minimum age to be employed in Missouri? The legal age to work in Missouri is 14, but governed by state and federal child labor laws and varies based on:

  • The type of work (e.g., agricultural or non-agricultural)
  • Whether the job is considered hazardous or has prohibited duties.
  • Whether school is in session.
  • The legal status of the minor (e.g., emancipated minors).
  • Whether the job is exempt from the Fair Labor Standards Act (FLSA).

According to Federal Law (FLSA), a minor must be at least 14 years old to work for an employer (e.g. retail stores, food service establishments and gasoline service stations), with an exception for minors working for a parent or legal guardian who owns the business. This is the reason why you will never see job postings for children under the age of 14.
