Its called the price of doing business. Women exist, they make up half of the the population and if men lose some weekends off in order to accommodate women then its a small price to pay for a progressive society.
So positive discrimination and inequality is now a cost of doing business?
Sorry but aviation is already hard for everyone you cannot start pulling those sort of stunts just to try and fulfill some gender quota. If some woman don't want to turn up 24/7/365 like everybody else then is it really the job for them? Not saying they aren't capable but
do they really want to do the job which includes missing birthdays christmas easters school holidays etc etc
Ultimately you can't have it all in aviation. If you want weekends and public holidays off go work for a bank or become a school teacher.
