the managers are well protected by their sponsors.
LAst week I had heard of a camp in Doha suburbs
populated mostly by indians and the company also run by Indians
where the workers had problem with regards to their wages and
food as well. Indian embassy had to intervene to solve at least part of
their problem.
During the time when they were low on food, one of the drivers of a Qatari living in that neighborhood used to collect whatever food was remaining in the surrounding Qatari houses and give it to these workers.

I dont want to name the exact location or company but this is a fact.
