No, rosters at EK are not stable (anymore). And no, I donīt get what I bid for (anymore)! Despite bidding the same way since years, the more senior I get, the less bids I get awarded, even not in my 2 top bid months.
And safety culture in EK? Hm...let me think...oh yeah, of course, our ASRīs are being taken serious, there is no fatigue here and we have a non-punitive reporting culture...
Seems you are flying for another EK than I...
