A labor rights group has released a new report about Apple suppliers in China. The report found that labor violations like those found in Foxconn exist in other supplier factories, and in many cases are much worse. The report found some workers worked 180 hours of overtime in a month, significantly higher than the 36 hour limit, and that some factories do not provide the required medical insurance. Apple says that it has conducted audits of the factories in the report, and has found some of the same conditions reported.
