  • A Department of Labor investigation found the operators of 14 Subway restaurants violated labor laws.
  • Teenage employees suffered burns after operating dangerous equipment, the DOL found.
  • The employers also didn't pay their employees regularly and stole tips, the DOL said.

The operators of 14 Bay Area Subway restaurants "endangered children" by making its teenage employees as young as 14 use dangerous equipment and work unlawful hours, an investigation by the US Department of Labor's Wage and Hour Division found.

The employers also didn't pay their employees regularly, issued "hundreds" of bad wage checks, and stole tips left by customers, according to the DOL.
