To ensure all of this work doesn't go to waste, we need ongoing pressure to sustain and improve on today's position. We need companies to focus on nurturing the next generation of female talent with executive leadership programmes and by allowing more flexible working arrangements and other family-friendly policies.
There has been a lot of fanfare this week around the reaching of the 25% target for women on boards. Lord Davies set this voluntary target for FTSE 100 companies back in 2011. It's clearly a good thing that boardrooms are getting more diverse and having a target has meant the whole issue has been in the news for the last few years.
I'm an old-school feminist. I joined the workforce a week after my 16th birthday, less than two years after the 1975 Sex Discrimination Act hit the statute books.
