Getting 20/10 if your family is in Jeddah is as useful as an umbrella in a desert.
And by right, all expats posted to Riyadh have to accept 20/10 ( I could be wrong here).
Which means that even though the forced Riyadh transfer may have been barely acceptable, the 20/10 and consequential salary loss would not !
Thus the 50-60 resignations ...
