Never called me on OFF days. I fly about 70 hours per month with peak of 90 in high season. I knew already though that aviation is seasonal stuff, but may still surprise someone
Have also to say that most of the time, on a 6/4 roster, you get the 6th day becoming OFF, so turning it to a 5/5, not bad for commuting if you have direct flights to your country. Even more because are for free.
As I said before, it is not the best company in the world, far from being, but it is not the kind of nightmare you depict. Might have been in the past, now is definitely different story, but don't wanna convince anyone. Enjoy my life and let the others do the same.
