I have travelled extensively in my career, throughout my 20's, (and early 30's,) across Western and Eastern Europe, the Americas, and also across the Middle East and far East. I never felt as uncomfortable anywhere as I felt in the UAE. (And middle east in general.) You always have to remember you are second best to men, always . Women are not regarded very highly there, you are beneath your man, and your children belong to the man and his family in most cases.
So as a woman, I definitely would not go to that part of the world again, even on holiday. Stories like the one about the woman who took tramadol into Egypt are enough to put me off ever going again. I have travelled happily on hols to Australia, and Brazil, and Northern Russia, this past couple of years, but I will never go tot the middle east again. Been there, done that (a number of times,) and never again. I am always worrying I may do something 'wrong,' and end up in jail for life.
I travel a fair amount still (for work and for pleasure,) but avoid the middle east now. There are also parts of Africa I will not travel to.
If I was a man though? Yeah I may consider the job, but the rules are VERY different there. He needs to be briefed first. Eg, if he has any medicines for any conditions, he will need to speak to the Foreign Office who will tell him what he needs to do. There are many laws that are different to our own. Even stuff like kissing in public, and the way you dress. And you cannot co-habit unless you are married. If you screw these kind of things up, you could end up in jail for a long time.
