Available at business-humanrights.org...an interactive platform that aims to track construction companies on their performance and action related to migrant workers’ rights in the Persian Gulf region. Based on a survey, it includes their direct involvement as contractors, or on account of links through business associates...this includes India-based and regionally expansive businesses Larsen and Toubro Ltd (L&T) and Shapoorji Pallonji & Co. Ltd. 

...of the 47 companies reached in the initial phase, 10 have responded and five more issued statements. Ten declined the survey. The remaining 22 are yet to respond—L&T and Shapoorji Pallonji among them. This is dismal, but hardly unsurprising for a sector that has opted easily for handsome earnings over what I imagine are humdrum ethics. There is also the matter of countries encouraging the flow of migrant workers to West Asia to combat unemployment at home, and twin it with earnings that migrant workers repatriate. Such countries often paper over methods employed by unscrupulous recruiters at home that form the first step in the cycle of exploitation. It all needs a nudge—even a handsome shove—to clean up.
