Amnesty International says that, to end chronic labour exploitation, Qatar has done almost nothing effective since it was chosen five years ago to host the football World Cup in 2022.
It says the abuses shame the Gulf state and football’s governing body, Fifa.
An estimated 1.5 million migrants work in Qatar, many in the construction boom fuelled by Qatar’s successful bid.
Qatar denies exploiting workers and says it has implemented a range of labour reforms.
Qatar’s migrant worker population is expected to reach two million within the next two years, Amnesty says.
“Too little has been done to address rampant migrant labour abuse. Qatar’s persistent labour reform delays are a recipe for human rights disaster,” said Mustafa Qadri, Gulf migrant rights researcher for Amnesty.
Amnesty said Qatar had failed to make changes in several key areas, including giving workers the freedom to change jobs, to leave the country and the right to join unions.
A May 2015 report by Amnesty identified nine fundamental migrant labour rights issues.
