The workers were eventually coaxed down after two days on top of their three-floor plant in Wuhan by Foxconn managers and local Chinese Communist party officials.
Foxconn, which manufactures gadgets for the likes of Apple, Sony, Nintendo and HP, among many others, has had a grim history of suicides at its factories. A suicide cluster in 2010 saw 18 workers throw themselves from the tops of the company's buildings, with 14 deaths.
In the aftermath of the suicides, Foxconn installed safety nets in some of its factories and hired counsellors to help its workers.
The latest protest began on January 2 after managers decided to move around 600 workers to a new production line, making computer cases for Acer, a Taiwanese computer company.
"We were put to work without any training, and paid piecemeal," said one of the protesting workers, who asked not to be named. "The assembly line ran very fast and after just one morning we all had blisters and the skin on our hand was black. The factory was also really choked with dust and no one could bear it," he said.
