Love the nonsense flying around on this thread.
Das Uber, you will find with a little research yourself that the government: police and defense for example, can use quotas when selecting candidates for positions. Oic made the point that the private sector cannot. You should be a little more careful with how you cherry pick quotes.
And Keg thinks the industry has done nothing to foster the massive workforce imbalance in the airline industry. How did such an imbalance come about then? Examining what can be done to encourage more women to join the industry should not imply the assignment of blame, no one is suggesting you are any individual is at fault for the state of affairs. The airline game needs to figure out how to make the industry more accessible to women and as someone has already suggested, that requires a grass roots approach. And a generational change. A quota system has merit in some situations but not this one.
Plus, a little research will quickly reveal that it's not legal.
