In a report published on Thursday, HRW also mentioned an array of international brands, including Marks & Spencer, Armani, Gap and Adidas, where workers have ostensibly faced sexual harassment, been forced to work overtime and have few opportunities to take a break.
The report cited interviews with workers at 73 factories in Cambodia, with some of them claiming that one of the H&M factories used children as cheap labor.
Other workers claimed that their productivity was allegedly being monitored on behalf of H&M.
"Some of the worst employment-related crimes happen at the larger factories' smaller suppliers. The reason is that nobody really investigates them," HRW researcher Aruna Kashyap said.
She urged the major retailers "to help labor law compliance by publicly disclosing and regularly updating the names and addresses of their factories."
Adidas and H&M, for their part, said that they are already publicly disclosing their suppliers and are already dealing with the problems mentioned in the study, according to HRW.
