Wintek -- screen supplier for Nokia, Huawei and Apple. The Taiwanese company's East China factory ground to a halt last Friday morning, while about 2,000 of its 10,000 workers went on a five-hour protest over a rumored bonus cancellation for the second year in a row. On top of that, workers also criticized Wintek for using n-hexane -- a banned substance used for cleaning LCDs -- which they claim caused the death and paralyzation of several workers last year. Factory officials and Chinese health authorities don't deny that n-hexane was used, but they say it wasn't responsible for either the deaths or the paralyzations. Now, the good news: Wintek has promised that workers will get their bonuses, and further said that the factory hasn't used n-hexane since August -- complete with proof that current n-hexane levels are lower than safety regulations require. Let's hope things get better between management and workers from now on. One more picture and video of the protest after the break.
