Ammon News - CNN - As Qatar goes on a construction blitz ahead of the 2022 FIFA World Cup, much of the new infrastructure will be built by migrant workers. And given Qatar's track record, that's cause for major concern, a human rights group says.

A new report from Amnesty International finds that worker abuse is rife in Qatar's construction sector. The report, called "The Dark Side of Migration," says some workers endure excessive and often dangerous working hours, squalid living conditions and have their payments withheld. One manager referred to workers as "cattle."

The report is based on interviews with 210 workers, 22 companies and government officials. It includes investigations into companies subcontracted by major organizations, including the government's Qatar Foundation and South Korean group Hyundai Engineering & Construction.

Amnesty said its researchers witnessed 11 men signing papers before government officials, falsely claiming they had received all payments and benefits to allow them to leave the country.
