…China Labor Watch sent undercover investigators to the factories, which altogether employ about 20,000 laborers…The report found instances of hiring discrimination, mandatory and excessive overtime work, unpaid work, broken labor contracts, poor safety measures and few paths for laborers to seek recourse. Many of these issues also break Chinese labor law.

…In a statement to Fortune, Hasbro spokeswoman Julie Duffy said, “We are aware of the China Labor Watch report and take their allegations very seriously. We require all Hasbro products to be manufactured in accordance with rigorous ethical standards, and that all third party facilities ensure employees have a healthy and safe working environment. Hasbro combines industry best practices, strategic partnerships, and strict auditing standards to respect the safety, well-being, and dignity of workers, and works continuously to ensure compliance with all third party facilities.”

Mattel spokesperson Alex Clark said that the company is in the process of reviewing the report. “In the meantime, I can tell you Mattel is committed to ensuring every single person making our toys and products is treated fairly, with respect and is able to work in a safe and healthy environment. Our labor standards, environmental, health and safety programs and oversight processes reflect this commitment, and we stand behind our record of ethical labor practices and environmental stewardship. We are devoted to ensuring that our manufacturing facilities throughout the world are safe and ethical places to work, and we reject any suggestion to the contrary.” [also refers to Foxconn]
