"China Labor Watch's newest investigation in October and November found that serious problems with excessive overtime continue at Samsung's suppliers," said Li Qiang, founder of the group, in an email. "Most of the time, they use student labor, and there are other problems. We will very soon release a new report."
In September, China Labor Watch accused Samsung of "illegal and inhumane violations" at its factories in China, and said that workers' overtime at the facilities could reach or exceed 100 hours a month. Chinese law currently prohibits overtime that exceeds 36 hours per month.
