• The US Labor Department filed a complaint against PSSI following a three-month investigation into unlawful child labor claims in November.
• PSSI was charged $1.5 million in penalties as a result of the investigation, officials said. 
• The department accused the sanitation contractor of having employees as young as 13 working "hazardous" overnight shifts.
