Can a 12 year old kid bag groceries for stores?

Child Labor Laws vary by state and country. In the United States, federal law prohibits children under 14 from working in most non-agricultural jobs, including bagging groceries. Some states have stricter laws that prohibit children under 16 or even 18 from working in retail stores. There may be exceptions for children who are working in a family-owned business or who have a special permit from the state. Please check with your state's labor department for more information about child labor laws.
