...As this report documents, dozens of...workers suffered abuse and exploitation while employed on key Olympic venues. This report is based on in-depth interviews with 66 migrant workers who...were employed in construction...on Olympic and other sites in Sochi. Migrant workers said employers subjected them to a range of abuses and exploitation, including: failing to pay full wages, excessively delaying payment of wages, and in some cases failing to pay any wages at all; withholding identity documents, such as passports and work permits; failing to provide employment contracts, or failure to respect terms of a contract; and requiring excessive working hours and providing little time off. In many cases, employer-provided housing was overcrowded, and employer-provided meals were inadequate. In several cases...employers retaliated against foreign migrant workers who protested against abuses by denouncing them to the authorities, resulting in the workers’ expulsion from Russia.
