I only wanted to say that QR would never take advantage of your illness by punishing you with horrible rosters following month. That is crazy for me because it never happened to me so I can't imagine it. Maybe it does happen, maybe it doesn't. I just know it never happened to me and my closest friends. I never heard anyone complaining about it either.
They probably wanted to know why you left your apartment 'if' you were sick, to see if you don't lie to them. Your boss in your country would probably ask you what you are doing outside if he finds you in the supermarket on the day you called in sick, wouldn't he?
There are power minded people everywhere, not just in Qatar who tells you what to do and think they are better than everybody else.
