If women want to have equality in the workplace, we have to share the responsibilities in the home better.
When Norway's policy was introduced, its gender pay gap was about 20 per cent. It has dropped to just 7 per cent.
Also helping to redress the balance is the fact that Norway has highly subsidised daycare with costs capped at around $450 a month for each child. Women know that when they enter motherhood, the barriers to continued employment are low.
It is worth noting that the gender pay gap is lowest in the bottom end of the earnings distribution but wider at the top. The top female earners still make 17 per cent less than their male counterparts, suggesting the continuing existence of the so-called "glass ceiling".
But women in Norway are far better represented in two key areas where Kiwi women lag. In Norway, women occupy 40 per cent of parliamentary seats and 40 per cent of board seats in listed companies. This is directly related to the introduction of the legal requirement in 2006 that both men and women have to make up at least 40 per cent of boards of companies listed on the stock exchange (and a range of other companies).
The tech industry is working hard to tackle discrimination and gender issues in a field so clearly dominated by men.
When Google's Sydney office was initially established, it famously had more people called "Dave" working there than women. Google is taking steps to address that issue, including limiting chances to negotiate salary because they recognise Karen Patterson's point (which is clearly established by research) that women are less likely to negotiate salaries.
Another legislative change which could be made is radical transparency. In the United States, some tech companies are getting rid of the secrecy surrounding pay altogether. If we all know what other members of the team are being paid, it is a lot harder for a firm to undervalue a particular worker.
A US-based software company, Buffer, makes all salaries, from the chief executive down to office staff, publicly available online. Any kind of bias is more likely to be seen and addressed.
Working mothers worried about the future of their children can be heartened at the news that women whose mothers worked outside the home are more likely to have jobs themselves, are more likely to hold supervisory responsibility at those jobs and earn higher wages than women whose mothers stayed home fulltime, according to a comprehensive study at Harvard Business School.
"There are very few things ... that have such a clear message on gender inequality as being raised by a working mother," says Kathleen McGinn, who led the study.
We live in a world where overt discrimination against women and working mothers no longer exists in the way it has for previous generations. The ongoing issues for men and women are reflected in the gender pay gap. The solutions include ensuring that the workplace is more family-friendly, improving the availability and quality of part-time and flexible working and investing in childcare to help individuals achieve a full work-life balance. Legislation can make New Zealand a leader in this area as it proudly has been historically.
