Frustrations erupted Monday night at a Foxconn factory in Chengdu, when a minor incident sparked a Foxconn workers riot against security guards.

Apple may have agreed to help improve conditions at Foxconn factories in China following recent protests, but the state of the Chinese factories appears to still be in disharmony.

Stemming from a minor incident involving a theft at a factory dormitory, the riot quickly descended into chaos as hundreds of workers reportedly joined in, throwing trash cans and destroying facilities, according to Want China Times. Authorities were called in to settle the crowd and arrested dozens of employees involved in the disturbance.

Foxconn, the world's largest electronics maker, has drawn sharp criticism for some time regarding its poor working conditions. Apple, who relies heavily on Foxconn to produce products like the iPad and iPhone, announced last month that it would share the costs of improving life quality and conditions for the workers with Foxconn Technology Group.

Despite promises of improvement, heavy workloads and harsh punishments seem to remain the norm at the factories, according to a recent report, which drew from 170 interviews with workers and supervisors.

This week's riot follows in the same vein of recent small-scale protests at individual factories around the country. Workers at the Wuhan factory continued to protest conditions in recent months by threatening to jump off the roof.

However, the Chengdu riot escalated to an extreme degree, involving up to 1,000 workers, according to Want China Times. The riot broke out in the male dormitory when security was called in to stop a thief. With tensions running high, other employees joined in the scuffle that ensued and took to the upper floors of the building to throw chairs, pots, bottles and fireworks out the windows.

The riot subsided after two hours once hundreds of police officers arrived and calmed down the masses, detaining some involved.

  • Handmade Gadgets

    On February 21, <a href="http://www.huffingtonpost.com/2012/02/22/nightline-apple-supplier-foxconn_n_1293393.html?ref=technology" target="_hplink">ABC aired a "Nightline" segment featuring Bill Weir's visit to a Chinese Foxconn factory</a> responsible for making some of Apple's popular devices. During a tour of the factory, Weir says he "expected more robots" but in fact most of the gadgets at Foxconn are made the old-fashioned way: The high tech parts are put together by hand. For example, iPhones are assembled by hand in 141 steps. One iPad takes five days to assemble and passes through 325 sets of hands.

  • Insane Output

    Two shifts of workers toiling in 12 hour shifts can make 300,000 iPad camera modules in one day, not to mention shape sleek iPads out of "raw hunk[s] of aluminum" at a rate of 10,000 per hour. <a href="http://abcnews.go.com/watch/nightline/SH5584743/VD55173552/nightline-221-apples-chinese-factories-exclusive" target="_hplink">Image via Nightline</a>

  • 7 To A Room

    Many workers live at the factory, where they pay $17.50 per month to live 7 to a room in Foxconn dormitories. <a href="http://www.forbes.com/sites/connieguglielmo/2012/02/22/nightline-goes-inside-apple-factories-in-china/" target="_hplink">The average starting salary is $285 per month,</a> and workers must pay for their food. <a href="http://abcnews.go.com/watch/nightline/SH5584743/VD55173552/nightline-221-apples-chinese-factories-exclusive" target="_hplink">Image via Nightline</a>

  • No Free Lunch

    Workers get two hour-long meal breaks during each 12-hour shift. They eat together in a cafeteria where they pay $.70 a meal. This is about a quarter of their hourly wage. <a href="http://abcnews.go.com/watch/nightline/SH5584743/VD55173552/nightline-221-apples-chinese-factories-exclusive" target="_hplink">Image via Nightline</a>

  • Tim Cook Investigated Suicides

    In 2010, after a spate of suicides at Foxconn's Shenzen plant, then COO Tim Cook flew to China to investigate the matter. <a href="http://abcnews.go.com/watch/nightline/SH5584743/VD55173552/nightline-221-apples-chinese-factories-exclusive" target="_hplink">According to Nightline,</a> Cook put together a team of psychiatric experts to examine the issue. It was at that team's suggestion that the infamous nets were installed between the buildings to prevent suicides. There have been 18 worker suicides at Foxconn since 2010. <a href="http://www.reuters.com/article/2012/02/15/us-china-apple-idUSTRE81E1FQ20120215" target="_hplink">According to Reuters' interview with Fair Labor Association president Auret van Heerden, the group's initial findings from its audit of Foxconn</a> suggested that the suicides could have been "a function of monotony, of boredom, of alienation perhaps."

  • Young Workers

    Weir said he was surprised to see how young the workers were. He said many were in their late teens and no one looked like they could be over 30. Many had left their hometowns, oftentimes in the countryside, in order to get jobs at Foxconn. Weir also toured Chengdu and spoke with the relatives of workers who had left for jobs at Foxconn. According to Cult of Mac, <a href="http://www.cultofmac.com/147878/foxconn-employees-say-underage-workers-were-hidden-before-fla-inspection/" target="_hplink">Foxconn may have hidden underage employees</a> when the Fair Labor Association conducted its inspections. While Apple allows for workers as young as sixteen to assemble their products, those eighteen and under are afforded "special protections," <a href="http://www.appleinsider.com/articles/12/02/22/factory_workers_claim_foxconn_hid_under_age_employees_before_fla_inspection.html" target="_hplink">according to Apple Insider.</a> These include not being allowed to perform some tasks and working shorter hours than older workers.

  • Foxconn Exec Wants To Pay More

    When asked how Foxconn would react if Apple suggested doubling workers' pay, Foxconn executive Louis Woo told Weir that the company would welcome a raise for employees. "Why not?" Woo said. "That would be good for the employees and also definitely good for China and good for us."

  • Air Showers

    Workers have to wear static-proof jackets and take "air showers" to make sure the work area remains dust-free. Even one spec of dust could prove ruinous to the iGadgets' delicate innards. <a href="http://abcnews.go.com/watch/nightline/SH5584743/VD55173552/nightline-221-apples-chinese-factories-exclusive" target="_hplink">Image via Nightline</a>
