because in general, the south african operators treat their pilots like sh*ite...pay peanuts, and we all know what you get.
but forsight is not strong or high on their list of priorities, hence you see the contracts doing the rounds of the contract companies....
a stepping stone to a serious job is all the contract companies can ever be because they dont offer anything serious to those who would have been serious about staying and working hard for the company.
just my opinion, but i think there are a few who might well agree...
