He Singingdude, bad mistake to relate QA to a Nazi concenration camp, these where specifically for the eradication of unwanted individuals, mainly Jews............what you are saying is bad but in no way related to what went on in the concentration camps.
Alot of these rules have been running around years in other Arab Airlines, I used to have a English girlfriend that worked as a Purser on Saudi Airlines, some of these rules were prevalent there too, no marriage in the first 5 years of employment, use of company supplied accomadation etc. Some of these rules are very hard and unfair but these are normally put infront of you to read before you take a job.
By the way the turn around in Saudi Airlines in staff was pretty high, people got there training there and then moved on to better airlines.
