In your case, better know somebody in the place.....
Recruitment is an organized chaos..... as other many departments though..... rostering, ops, HR, housing, but if you happen to know someone to sell your soul to, your life will be nice, as nice as the others one will be bad.... but expats are selfish, aren't they......that's what management is counting on, and it works.....
No need to recruit more .... just roster the one we have to the limits and even more if we can....legality is just a word, if the pilot accepts and there is a problem, guess who will be fired ??? the crew controller and the pilot, not the damn useless c######l manager.... fill the blanks....
