Why should a female pilot not be entitled to the same quality of life in terms of part-time working as for instance a bank clerk?
Because she chose to work in a profession that involves responsibility for people's lives as well as very expensive equipment.
You make it sound as if she was forced to become a pilot, and therefore ought to be entitled to "compensation" for the fact that she has a tougher job.
If she wants the flexibility granted to bank clerks, no-one is stopping her becoming a bank clerk. But people have to get this ridiculous idea out of their heads that the conditions of one job should apply equally to another job - particularly when the responsibilities involved are so wildly different.
My job often requires me to work abroad for several days at a time, often at short notice, and to work through holiday periods while my mates are getting trolleyed.
It's not my employer's fault that the nature of my job doesn't fit a cosy 9-to-5, home-to-the-wife framework. I choose to do this for a living - and therefore I have to accept the disruption. If I don't want to put up with it, I don't have to stay - there's plenty of people who'll gladly step into my shoes.
