You can leave the country on Days off.... you just need a Multi-exit-visa (500QR) and you get it after 3 months. Also, b4 3 months you have to ask if you can leave and get a single exit visa.
You are not allowed to date hosties. Get caught screwing the crew or if someone doesnt like you and reports your indiscretion, then you will have a very high chance of being sacked.
Cant live together with a opposite sex unless your married.
You dont need to wear a hat in the taxi. I have never been told about that.
You dont get sacked immediately for an unstable approach unless it was clearly blatent defiance of the SOP's. You will get questioned generally. But yes, sacking are high here, but partially can blame alot of the SOP's changes and the fear of more rumour and not enough facts.... this not enough facts is simply by the complete lack of communication problem here...... its company wide issue.
