According to the China Labor Watch, clashes led to the shutdown of 4,000 employees in one of the Foxconn, Apple's main partner in assembling iPhones 5 and several other Ma devices.
The great pressure on factory workers, who need to meet demanding quality standards, has heated up clashes between employees and inspectors in Zhengzhou, China. In addition, other factors such as the deprivation of holidays and holidays during the Christmas period and the lack of technical training may have contributed to the shutdown.
Some employees were injured during the clashes which damaged inspection rooms and some were even hospitalized.
