I would say, it is the lack of support from management on the personal field, we are all humans and at some point we need a customized solution to our problems, and in the middle east you are an overpaid slave... we westerners are used to explain a situation to management and get a reply saying hpw you can you be helped or why they can't, and this is the most fustrating thing knowing they have the resources, but no will to help you.
