Okay then, let's make this post a little more interesting.....
I wonder how many Muslim pilots don't work during Eed?
I wonder how many Hindu pilots don't work during Diwali?
I wonder how many Catholic pilots don't work on Christmas Day and/or Easter Sunday?
The point I'm trying to make here is that working any time throughout the year is absolutely fine - but a religious festival / ocassion - surely airline management have some sympathy / leniency?
