For Ahnaf and Christian - both have asked to be anonymous and have fake names - this is their first visit to Sweden.
Originally from the Philippines and Bangladesh, respectively, they are in place in connection with the trade union Building Congress at Arlanda to give their picture of the working conditions in Qatar.
Because when world stars run into some of the World Cup arenas, it is Ahnaf, Christian and their colleagues who built these, as well as all the infrastructure in connection - roads, bridges and luxury hotels.
The total cost is said to be a staggering $ 200 billion, according to various estimates.
The humanitarian suffering is as difficult to grasp as the astronomical calculations, with reported deaths of up to just over 6,000 guest workers, according to The Guardian.
- It is tough during the summer, very hot, about 40 degrees heat but sometimes up to 50 degrees.
You work every day of the week except Friday, it can be 12-14 hours working days, says Ahnaf.
Long journeys
Then the long journeys are included.
Many migrant workers who come from Asian countries are housed in barracks and transported from there to the construction sites themselves.
- Previously, it was the case that you did not get paid for the actual travel and it could be travel of two hours - easy way, says Christian.
- On one occasion, a road construction was shut down, where 5,000 migrant workers worked for whom no salary was paid for six months.
Many of these do not know what applies and the countries' embassies also do not know how many people live there or work in the country.
The workers have been sent there by various agencies, says Christian.
An association
Despite protests against the conditions, it is highly probable that they have no effect but instead cause the migrant workers to end up outside the system and without pay.
