@kondoo,
You are a real sheep. Yaani you still believe in that job security in the civil service crap? there is no such thing. And why would a young fellow with a whole life lying ahead want to slave for anyone till 60?
My advice: take the study opportunity at hand and go. Aim higher than than your current job and you will surprise yourself. The civil service will be still be here when you come back,in case you are still inclined to rejoin after the shabby they have treated you.
I can tell you I quit a so called safe job with GOK many years back and I have never regreted my decision.
