The Qatari authorities say they have increased inspection of accommodation, but I visited four so-called labour camps in Doha and they were all squalid.
Some were better than others, but they were all overcrowded with around six to eight men to a room.
Twenty and sometimes up to 40 men have to share a kitchen, which is often just a few cooking hobs hooked up to gas canisters and nothing more.
The toilet and washing facilities are so basic and dirty that some men use buckets of water to wash.
One Bangladeshi man said that raw sewage had been leaking into the camp from a broken pipe.
The Qatari authorities say: "There are very many developments for new workers’ accommodation in Qatar at various stages of planning and construction, including at Al-Baraha (25,000 beds); and the Barwa Recreation City facility at Al Khor, which will accommodate a further 6,000 workers, and recreational facilities.
"Further private sector developments will create a further 70,000 beds for workers; while enforcement and inspections should help raise the standards of existing accommodation."
’21st Century slave state’
The 2022 World Cup has kicked off a multibillion-dollar construction boom in Qatar, and roads and hotels are being built to accommodate the fans and businesses that will flock to the emirate.
But though Doha, the capital, looks uber-modern, with glittering skyscrapers and innovative architecture, its labour system is less forward-looking.
