Just a note here,
The reason that Ethiopian is employing expats in such numbers, these last years, is because of the continuous exodus of 737 & 767 captains, to ME and Asia! Their salaries are frustrating low, that should explain part of this behavior to expats. Their training methods though is prolific and some training captains and captains treat their local FO same way they treat expats. It's a cycle of a system that expats got in to.
