The supposed reason being "bandied about" by GM Flying & VP Flying for the "delay" or NON payment of the Contract Completon Bonus is that it is "according to a recent Royal Decree". Well, at least that is what is being relayed is the reason being given by SV HR Department.
However I find it very hard to believe, that if correct, the "decree" can be retrospectively applied to contractual agreements already signed and in existence. It will need someone, or a group, to challenge Saudia in the Saudi Labour Court.
