I mean it's not like we don't know the unions exist, and it's not like they don't recruit. So if we wanted to join them, nothing's stopping us.
The unions find this figure disappointing - and I guess you would if complaints are your stock and trade, but if people are happy to negotiate their own way in the world, why would we be upset by that?
Maybe we all feel more empowered as individuals these days and unions have had their time?
It is a good reminder of how much something gets a spotlight, and in theory can loom large, versus the reality: which is often less impressive.
It reminded me of another story I read this week on feminism.
In these times of heightened awareness of all issues female and women's empowerment would you not expect numbers on feminism to be at an all-time high?
Well the reality is they're not.
In fact the numbers of people calling themselves feminists is dwindling.
Polling in the UK and the US showed fewer than 1 in 5 young women would call themselves feminist.
Is that not surprising? Is this not a time of peak global awareness of women's rights, the #MeToo movement, body positivity, calling out sexism?
So how has identifying as 'feminist' not gained more traction?
A US study of 27,000 people found that two-thirds of respondents believed in gender equality - but when it came to the term 'feminist', many found it unrelatable.
So do unions, and the feminist movement, need to work harder to attract a more diverse group of people?
Do they need to redefine themselves as more inclusive?
Or are we all just a bit more comfortable in our own skin these days?
