The managements point of view. Having expats and paying a few bucks extra is worth it. As they can get away with any thing. No one will complain. The expats are like dogs. With only Yes sir and no sir.
They could get an expat to do what they want. If you have more locals this is a major bug. So why get the expats out. And the management guys can work till their great grand children get jobs.
Infact this has been informed to the CEO. That's why he too does not want any expats sent.
