In a letter sent to FIFA President Gianni Infantino on Sunday night lawyers acting on behalf of the FNV and Alam give the football body three weeks to admit complicity and pay damages, otherwise the case will go to court.
While the damages sought by Alam are reported to be relatively modest, if the action is successful, it could set a legal precedent and open the door for thousands of other laborers to make similar claims.
The lawyers also call on FIFA to acknowledge that it acted wrongfully by awarding the World Cup 2022 to Qatar without demanding the assurance that Qatar observes fundamental human and labor rights when it comes to migrant construction workers who work at the sites prepared for the tournament.
FIFA did not react publicly to reports in the media, but the organization has so far denied responsibility for living and working conditions on World Cup construction sites, claiming it does not have responsibility for wider societal problems in the host countries.
Qatar has been under fire from human rights organizations in recent years for alleged mistreatment of migrant workers, including those building the stadium and other infrastructure for the World Cup the country is to host in 2022.
