The policy brief focuses on the working conditions in Thailand's hard disk drive industry and in  meant for stakeholders that are interested to get to know more about the working conditions in  this sector. In May 2007, SOMO published a research report on the labour conditions in the Thai electronics sector: “Hard (Disk) Labour, Research Report on Labour Conditions in the Thai Electronics Sector”.  This policy brief follows up on this research report. The operations of three companies in this sector in Thailand are reviewed. The first two are Seagate and Western Digital, respectively the largest and second largest HDD manufacturer of the world. Together, the two companies employ more than 50,000 people in Thailand, predominantly women. The two companies outsource parts of the production process within Thailand. An example of this outsourcing is provided by the Donaldson company, which supplies filters for the disk drive industry. For this policy brief, Donaldson was also reviewed.
