Sorry Harry, many trainers I know use their days off to commute. Many, many.
And further Harry, when I went to the interview days, 10 years ago, rosters were shown to us that we were told were "commutable'.
That's what some of us went there for, because family circumstances did not allow for our family to live in the UAE, but the prospect of commuting made the job attractive.
The contract that I signed, and the job I left, resembled nothing, except I flew an aircraft.
Harry, you really need to take a good look on others positions.
