Reuters  reports that a group of Wintek employees that were poisoned during the manufacture of Apple products by the N-Hexane cleaners that their company used are making a direct appeal to Apple CEO Steve Jobs.

Apple noted that Wintek had used the chemical in its yearly Supplier Responsibility Progress Report and the company had discontinued its use.  Apple declined to comment on the workers’ letter and referred a reporter back to its supplier report.

Wintek said it had used the chemical, which evaporates faster than alcohol, to speed up production of touch screens for Apple products. It has since gone back to using alcohol.

It wasn’t immediately clear what the workers were after.  The note, addressed to Apple’s CEO is pasted below:
