The FIFA board session next week could decide "in principle" that the 2022 tournament cannot be played in the Qatari summer, FIFA President Sepp Blatter has suggested.
Burrow said FIFA had promised after a November 2011 meeting to do something about the labor conditions within six months.
"They failed," she said.
Burrow wrote in a Sep. 20 letter to Blatter that "several hundred migrant construction workers die each year in Qatar" where they often work in extreme heat. Burrow spoke of 1.2 million migrant workers in Qatar, many laboring in extreme heat long hours, little pay and without legal protection.
In the interview, she said that the construction of stadiums, hotels and other facilities would easily add to that.
Without changes in the labor conditions, "the minimum estimation, the very conservative estimation from our side is that 4,000 workers will die before a ball is kicked," she said.
The ITUC is a global trade union group uniting 178 million workers in 156 countries.
