A new report says that a MacBook factory in Shanghai continues to face turmoil and that some of its workers have revolted against their overseers.

Bloomberg reported Friday:

Violent clashes, mounting infections and vacant factory floors: the turmoil that’s engulfed tens of thousands of workers at an Apple Inc. supplier in Shanghai is a troubling symptom of China’s extreme efforts to keep factories humming during its worst Covid outbreak since 2020.

The report says that workers who have been “trapped in a bubble for almost two months” are “demanding more freedom and beginning to revolt against their overseers.”

The report cites shocking video footage that emerged earlier this month and claims another incident took place in the last week:

Hundreds of workers have clashed with guards. A large contingent, worried that their supplies would run out should the lockdown persist, flooded past guarded isolation barriers earlier this month in search of daily necessities, according to several employees. Over the past weekend, media reports went viral of a large group storming a dormitory housing Quanta’s Taiwanese managers after a dispute over the prolonged lockdown and pay — triggering an hours-long standoff confirmed by several workers within the compound.

One worker said people were getting “frustrated and tired” of these controls, referring to lockdown measures in the region stemming from China’s strict zero-COVID policy. Most factories in the region are operating “closed-loop” policies, with workers only allowed to travel between factories and accommodation, or worse being housed in the factories themselves.

Unfortunately, it seems that a COVID outbreak began right before April lockdown measures, with the factory’s close conditions actually aiding the spread of the virus and starting a local outbreak.

Apple is facing long delays across many models on its Mac lineup including the MacBook Pro (2021), of which Quanta is a key supplier. You can read the full report here.
