Expatriate laborers held a protest in downtown Kuwait on Sunday to demand payment of their salaries they say are three months overdue.
According to a report in the Kuwait Times, almost 700 workers gathered outside the Labor Ministry complex to call for an intervention by the authorities.
The workers said they have not been paid since June, nor received any payments for overtime worked in almost a year, and are now struggling to cope under huge debts.
Many protesters told the paper they were working with out-of-date visas after their employers failed to renew them.
The three major construction companies, which were not named by the paper, are also accused of withholding passports, not allowing them to resign, or travel home to visit their families.
