Presumably someone who has assessed the working conditions and limited legal protection available, and decided that the substantial renumeration package outweighs these negatives? Perhaps a controller who now has no job having been made redundant from a notionally secure country infrastructure, and finds the idea of continuing their chosen profession, albeit in a different country, appealing, or indeed necessary. Perhaps someone with a limited time left before retirement who would like to boost their income for a few years? Perhaps even someone who ignores all the small print and sees the headline package. I'm fairly sure there will be takers.
