Its all part of Aramco's "get cheap" policy. They have adopted the Exxon HR model. If you need an employee that costs X, hire two and pay them 50% of X. One will probably leave or be useless and get downsized, but then you have the other at 50% of the cost.
I quoted someone from one of the threads below because I totally agree. Aramco seems to be copying Exxon in everything that is not good?
