The word at the Orval is, 'Only go if your only other option is to shoot yourself!'
The Ts & Cs are appalling (apparently).
The pay is only just adequate – unless you're used to living in third world Africa, when it might seem a little better.
The rostering is a joke. They purport to run a 30 day scheme, however, it's always being changed and you'll only get the new one about six hours before the old one expires.
Do not bother to book leave. If you do, it can, and will, be cancelled anytime up until your departing aircraft rotates.
Always expect to work your days off.
Always expect to be called out on standby. Your local indigenous colleagues will go sick at the drop of a hat. (Dinner party, birthday, special day for a relative six times removed, etc.)
Do not be surprised if, in the middle of giving an in-flight briefing, your colleague gets out of his seat and starts to pray in a back corner of the flight deck.
Do not complain. This will be construed as an insult.
Bahrain is a great place, so long as nothing goes wrong. However, don't forget that you won't be there very much and will be spending most of your time down the route in countries about which you may not want to read.
