Large scale protests have erupted at the World’s biggest iPhone factory in the Chinese city of Zhengzhou.
According to videos circulating on Social Media on Wednesday, hundreds of workers were seen marching with some confronted by people in hazmat suits and riot police.
It was reported that last month, a surge in Covid-19 cases saw the company lock down the campus, prompting some workers to break out and return home.
The company then recruited new workers with the promise of generous bonuses.
According to the videos, the workers were heard shouting: "Defend our rights! Defend our rights!" while others were seen smashing surveillance cameras and windows with sticks.
Several clips also showed the workers complaining about food they had been given and saying they had not received bonuses as promised.
A worker said; "They changed the contract so that we could not get the subsidy as they had promised. They quarantine us but don't provide food,"
"If they do not address our needs, we will keep fighting."
The worker also claimed to have seen a man "severely injured and [who] might die" after a beating from police.
One employee who recently started working at the Zhengzhou plant said the workers are protesting because Foxconn had "changed the contract they promised".
He said some newly recruited workers are scared of getting Covid-19 from staff members, who have been there during the earlier outbreak.
"Those workers who are protesting want to get a subsidy and return home," the staff said.
There was a heavy police deployment to the plant on Wednesday morning, he added.
Other live-streamed videos also showed crowds of armed police at the site.
Another newly recruited employee said he visited the protest scene on Wednesday, where he saw "one man with blood over his head lying on the ground".
"I didn't know the exact reason why people are protesting but they are mixing us new workers with old workers who were positive."
Foxconn is yet to comment on the protest.
It was reported that in late October, many workers fled the plant amid rising Covid-19 cases and allegations of poor treatment of staff.
