- Summary- Companies- Online images show hundreds of workers protesting- Surveillance cameras and windows smashed by men with sticks- Workers complain of delayed pay, insufficient food- Foxconn says working to prevent repeat of violenceSHANGHAI/TAIPEI, Nov 23 (Reuters) - Hundreds of workers joined protests at Foxconn's (2317.TW) flagship iPhone plant in China, with some men smashing surveillance cameras and windows, footage uploaded on social media showed.The rare scenes of open dissent in China mark an escalation of unrest at the massive factory in Zhengzhou city that has come to symbolise a dangerous build-up in frustration with the country's ultra-harsh COVID rules as well as inept handling of the situation by the world's largest contract manufacturer.", chanted workers who were surrounded by people in full hazmat suits, some carrying batons, according to footage from one video.A second source familiar with the matter, however, said Foxconn was unlikely to hit the target, pointing to disruptions triggered by the unrest, impacting particularly new recruits who were hired to bridge the gap in the workforce."It's now evident that closed-loop production in Foxconn only helps in preventing COVID from spreading to the city, but does nothing (if not make it even worse) for the workers in the factory," Aiden Chau of China Labour Bulletin, a Hong Kong-based advocacy group, said in an email."
