I've never been asked if I want to work overtime, it has always just appeared on my roster. Sometimes in large quantities. I don't think I would get very far if I called crewing and said I actually didn't fancy any overtime this month. Working days off is a different matter. I don't, because I have a life outside EK which is worth more to me than the couple of Dhs I get for giving up a day off. If the people who are complaining about fatigue are working days off then I don't have any sympathy for them but I suspect that, like me, they are simply having overtime thrust upon them.
