Protests have erupted at the world’s biggest iPhone factory in the Chinese city of Zhengzhou, according to footage circulated widely online.
Videos show hundreds of workers marching, with some confronted by people in hazmat suits and riot police.
Those livestreaming the scene claimed workers had been beaten by police.
Last month, a surge in Covid 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.
Footage shared on a livestreaming site showed workers shouting: “Defend our rights! Defend our rights!” Other workers were seen smashing surveillance cameras and windows with sticks.
Several clips also showed workers complaining about food they had been given and saying they had not received bonuses as promised.
“They changed the contract so that we could not get the subsidy as they had promised. They quarantine us but don’t provide food,” said one Foxconn worker during his live stream.
“If they do not address our needs, we will keep fighting.”
He 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 also told the BBC workers were protesting because Foxconn had “changed the contract they promised”.
He said some newly recruited workers also feared getting Covid from staff who had been there during the earlier outbreak.
“Those workers who are protesting are wanting to get a subsidy and return home,” the staff member said.
There was a heavy police deployment to the plant on Wednesday morning, he said.
Other livestreamed videos also showed crowds of armed police at the site.
Another newly recruited employee told the BBC 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,” he told the BBC.
Foxconn has not yet commented. It is Apple’s main subcontractor and its Zhengzhou plant assembles more iPhones than anywhere else in the world.
In late October many workers fled the plant amid rising Covid cases and allegations of poor treatment of staff, their escape captured on social media as they rode lorries back to their hometowns elsewhere in the central Chinese province.
Foxconn then attempted to convince workers to stay and to recruit new staff by offering higher salaries and bonuses.
The firm has since enacted so-called closed loop operations at the plant – keeping it isolated from the wider city of Zhengzhou because of a Covid outbreak there.
Earlier this month Apple said it expected lower shipments of iPhone 14 models because of the disruption to production in Zhengzhou.
