Lorries backed up at the border and flights were grounded for a second day in Kuwait today as workers continued strikes for better pay.
Flag-carrier Kuwait Airways canceled flights as it struggled to cope with the action by staff, who demanded the government honour a pay deal agreed more than six months ago.
Incoming and outgoing flights on over 20 routes to both regional and Western destinations were hit.
Kuwait Airways union rep Abdullah al-Hajri said workers would stay out until "our demands that were previously approved by the government are met."
A separate strike by customs workers stopped hundreds of lorries from crossing the border, causing some supermarket shelves to go bare.
They walked off the job last Tuesday, saying that a 25 per cent increase to their basic pay wasn't enough.
Customs workers' union official Marzouq Awwad said at the weekend that the walkout will continue until bosses come up with a better deal.
Power plant employees and university professors are also threatening to strike unless they too get increased pay and retirement benefits.
A government guided by common sense would respond to news that publicly owned Royal Mail has increased profits to £403 million by scrapping plans to flog off the service.
