Yes, this is correct. In Australia the gender pay gap hovers around 20% in the private sector, there is ample data out there in support.
People love arguing this point. While there is
some merit, one can make statistics seem whatever they want to support their point of view.
Lets ignore that the 20% gap comes from averaging out salaries. I could quite easily survey 10 males doing the same job across 10 different private sector companies and I can guarantee you that there will be quite a spread in salaries. It all comes down to negotiating ability and the individual company.
Statistically speaking males ask for pay rises more than their female counterparts. Unfortunately we live in a capitalist world, so you might be doing a stellar job but unless you ask you're not going to get anything. Why should an employer spend more money for you to do the same job you're doing now? Yes, some employers will show their appreciation with their chequebook without being prompted,
some.
Now back on subject, unless of course you have hard evidence that females are being paid 20% less
in aviation.
