There are studies which have shown companies with more diverse boards are more likely to make bigger profits. There are companies investing in programmes to try and increase the diversity of their workforce. I am not sure that these programmes are having as much effect as would be hoped for.
The area I'm most aware of is IT, but we're not getting hordes of women applying; if anything, it worse than a decade or more ago. The percentage of women on university Computer Science courses was at a peak in the late '80s - it's mostly been going down since then. And if we're not getting them in at the start, they're not in the pipeline to be mentored and trained and prepared, and those who are, there's a lot of attrition in their 30s and 40s women take maternity breaks or get made redundant, which forces them to review their career paths, and quite a few think, I just can't be arsed with fighting for everything, when my male colleagues don't have it half so hard.
So there's part of me thinking, I don't know if I should be speaking to people at schools, to get them to consider roles in tech, because these days, whatever their interests, there's probably an area of tech where they can work with those interests - plus as well as being interesting, and always with something new to learn, roles are well-paid (it's male-dominated), and can be flexible, so it should be good for parents. There is a need for aother more people to enter technology careers, male and female, and all the efforts to encourage women don't seem to be having a very big effect. And sometimes I think, I amdoing them no favours by encouraging them, because they're still having to fight against all the men who are hiring and firing and deep-down, don't think women are actually as good at men, so mediocre white men prevail and promote each other, and they seem to be impervious to efforts to change their mindsets, so they're not going to improve the balance by themselves, which is why some form of positive discrimination is needed, be it quotas or otherwise, unless they suddenly start realising that inadequate male managers are reflecting badly on all the men in the workplace and fix it spontaneously.
