The link has a rather nifty application where you can jot down your annual salary and it will calculate the annual salary that you'd get if you were a man doing the same job (for example, if you're a woman earning $20,000p.a., you'd get paid another $3,200p.a. if only you were born male) and vice versa.
To be honest, although being pro-closing the pay gap, I never really thought about how it affected me. Given I'm currently an undergraduate working mostly as a casual worker, I assumed the pay gap wouldn't be all too big just yet. Heh, I was wrong.
It turns out that, if I were doing what I already do - but was a man - I'd earn annually enough extra cash to go have a comfortable holiday somewhere like Byron Bay each year. Or, I'd have that little bit more money to put towards that car which I'll need when I move out of the city next year. (It might help me sleep at night, knowing I don't have to feel like I have to compromise my study by working every possible shift that comes my way!). That c17.5% adds up to a lot!
