We call it outsourcing. This has been the corporate mantra for quite a while.
Here in the US it does not matter if they save a lot of money.
Years ago, only mechanics/engineers were allowed to perform pushbacks.
Even if a jet crashes and many people die, the 'hull loss insurance' absolves the corporation and Upper Mgmt from any blame, in a legal and financial sense.
Too bad that we can't outsource some Upper Managements.
We would save large piles of money.
No 'golden parachutes' with 'zero-zero ejection seats'.
