Construction companies operating in the Gulf are failing to protect migrant workers from abusive working arrangements, showing a concerning lack of transparency on the safeguards they have in place, says Business & Human Rights Resource Centre...The Centre quizzed 100 construction companies operating in Qatar and the UAE on the measures they are taking to stop exploitation of migrant workers.  Only 22 responded, indicating a shocking level of inaction. The Centre today releases a report, “Wall of Silence” (attached) analysing the company responses, and a searchable online database in English and Arabic...All five companies headquartered in South Korea with projects in Qatar or the UAE [that we] contacted failed to respond: GS Engineering & Construction (E&C), Hyundai E&C, Lotte E&C, SK E&C, Ssanyong E&C, and Samsung Construction & Trade (C&T).
