Qatar World Cup organizers have admitted that workers were exploited while contracted for FIFA's preparation tournaments in the Gulf State.
The acknowledgement of failings came after an investigation by Amnesty International which said security guards were forced to work in conditions it called "forced labor" by exceeding the 60-hour maximum work week and not having a day off for months or even years.
Qatar provided no details of the abuses that involved subcontractors working on the Club World Cup and Arab Cup in 2021.
"Three companies were found to be non-compliant across a number of areas," Qatar World Cup organizers said in a statement.
"These violations were completely unacceptable and led to a range of measures being enforced, including placing contractors on a watch-list or black-list to avoid them working on future projects -- including the FIFA World Cup -- before reporting said contractors to the Ministry of Labor for further investigation and punitive action."
The exploitation of workers continues in Qatar despite World Cup organizers saying it has introduced measures since 2014 -- four years after FIFA awarded it hosting rights -- to protect health and safety.
"Many of the security guards we spoke to knew their employers were breaking the law but felt powerless to challenge them," said Stephen Cockburn of Amnesty International. "Physically and emotionally exhausted, workers kept reporting for duty under threat of financial penalties -- or worse, contract termination or deportation.
"Despite the progress Qatar has made in recent years, our research suggests that abuses in the private security sector -- which will be increasingly in demand during the World Cup -- remain systematic and structural."
The draw for the World Cup took place in Doha last week ahead of the Nov. 21-Dec. 18 tournament.
"FIFA must focus on doing more to prevent abuses in the inherently perilous private security sector, or see the tournament further marred by abuse," Cockburn said. "More broadly, FIFA must also use its leverage to pressure Qatar to better implement its reforms and enforce its laws."
