In March, the Labor Department fined a Tennessee manufacturer nearly $300,000 for employing minors to operate dangerous equipment.

Tuff Torq Corp., which makes components for lawn tractors and outdoor power equipment, also must set aside $1.5 million in profits for the 10 children it employed, according to a consent judgment entered in U.S. District Court for the Eastern District of Tennessee. Children as young as 14 were subject to “oppressive child labor,” according to a department press release.
