The committee responsible for the football World Cup in Qatar says a new "workers' charter" will protect labourers.
Dario Cadavid, Assurance and Integration Senior Manager, Qatar
2022 Supreme Committee, said worker safety was of "paramount importance".
However the International Trade Union Confederation (ITUC) said it was "very disappointed".
The ITUC's Sharan Burrow said the charter will not help migrant workers.
Ms Burrow was critical of a process under which, she said, "none of (the) documents have been released to the public or discussed with unions, and workers remain in the dark about their rights".
The charter was announced at a conference of the Institute of Occupational Health and Safety (IOSH) held in the Qatari capital Doha on Wednesday.
Mr Cadavid told the conference: "We look forward to a long-term partnership with IOSH to ensure a lasting legacy of worker welfare standards in Qatar."
