A new ACTU analysis shows women in full time jobs now earn $100 a week less than men and that the pay gap for working women is getting wider.
Full time women now earn on average 10% less than men - the same gender pay gap as 1978, almost 30 years ago.
ABS data also shows the real wages of female workers has fallen 2 per cent over the last 12 months.
Commenting on the worsening situation for women workers, ACTU President Sharan Burrow said today:
"On the eve of International Women's Day (Thursday 8 March), the ACTU calls for a renewed focus on women's pay and their working rights in Australia.
The Federal Government is presiding over a significant worsening of women's right to equal pay and the right to family-flexible working conditions.
With almost one in four women (23%) reliant on awards (compared to only 15% of men), the erosion of award conditions like penalty rates, leave loading and public holiday payments is having a serious impact on women's take home pay.
The Federal Government's refusal to include in the new minimum legal standards rights to family-flexible working conditions that were won in the Work and Family Test Case has also been a major setback.
It is a disgrace that Workplace Relations Minister Joe Hockey has denied there is a problem with unequal pay, instead he has expressed pride in women re-entering the labour force into low paid jobs in the retail and hospitality sectors.
The Minister should not be proud of a system where mothers returning from parental leave are expected to work in the lowest paid jobs in our country and have the least job security and least control over their hours of work. He should be ashamed," said Ms Burrow.
