"be a slave means" they will ask you to fly without schedule and sometimes they taken away your leave days.
"horrible apartements" they put you in middle to low class apartement in Kolkata which very filthy, even local pilots won't stay there, that is why they put all expats in Kolkata.
"60 hours/month" this for some expats, the roster can't manage to equalize hours in month, if they manage maybe you fly less than that, but since it has to be seen by Jet Airways management that everybody flies, so "some" expat fly more and "some" fly less, what I mean "some" there only less than 10 expat working there everybody leaving.
