If you're a professional (or even just a working) woman, the gender pay gap is surely one of the most singularly frustrating inequalities that we are faced with. And judging by the latest figures from the Workplace Gender Equality Agency, we've still got a lot of work to do. According to the agency's annual figures, women still earn 23% less than their male counterparts. Encouraging, right?

Even though this is a 1.6% improvement on last year's figures, for women in full-time work, this 23% less equates to about $27k a year less than men. And the figure gets even worse when you look at top-level management - we're talking $93,884. That's nearly 100k less, for doing exactly the same job.

Gender pay gap: men earn HOW MUCH more than women?

According to the data, which looked at over 12,000 employers and 4 million workers, certain industries were worse than others. Industries with the largest pay gaps include the financial and insurance services, real estate and construction - not surprising, considering these 'boys club' enterprises can be very male dominated. Industries with the smallest wage gap include education, wholesale trade and public administration and safety.

All in all, we think it's a pretty pathetic. Despite movements to address this, such as Sheryl Sandberg's Lean In, Jennifer Lawrence's Lenny essay and #GirlBoss (although, given Sophia Amorusa's bankruptcy status maybe that's a bad example), the difference in pay is still astoundingly depressing. We wonder if soon-to-be First Daughter Ivanka Trump, who this week vowed to fight for wage equality, will start her own war on the issue?
