I don't know why posters are pretending that women are systemically prevented from reaching the top - they aren't. There are about 27 million people in employment in the UK. That's about 14 million men (52%), and 13 million women (48%). Of the 893 directors of FTSE 100 boards in 2021, 393 were women (44%). There's still some room for improvement, but it's really not that far from equal ...
Adjust the ONS labour force survey figures for all those industries where men still predominate (energy, mining, agriculture, construction, manufacturing, oil and gas, waste), and women will actually outnumber men in a great many of the environments in which they work - traditionally health, education, adult social care, but also in managerial and technical professions too. The graphic below is from Mar 2022 parliamentary report on women in the UK economy. Women are employed in professional occupations in almost identical numbers to men.
The only really skewed distributions are skilled trades, care work, and admin/secretarial, which in the context of this thread is highly ironic. If you were looking for an admin person to fetch coffee, then that person is 2.5 times more likely to be female than male. Yes, assuming that the only female in the room is that admin person might constitute bias, but if that assumption is 2.5 times more likely to be correct than incorrect, then the number of occurrences need to exceed that factor of 2.5 to amount to evidence of systemic bias, and based on this thread, they don't.
In much the same way, a male primary school teacher may be mistaken for the janitor by the parents at the school gate. Or a male nurse may get mistaken for the porter or orderly by patients and family members. I'm sure it happens frequently - and it's no big deal, because it's just a mistake. A common one, perhaps, but it is still a mistake. To respond with passive-aggressiveness is utterly unprofessional and is a much clearer pointer why some people don't promote than their sex. And to be quite clear - if someone knows the truth and still behaves in a way that disrespects someone's expertise, that is clearly unacceptable and should be called out. But filter out all the instances on this thread where the behaviour described was a one off, or happened on a first encounter, or it was a long time ago, or those where the aggrieved person quite inexplicably went along with it and said nothing ... and this thread gets quite short indeed. And the voices of the women stating that this has never happened to them become a more significant contribution to the overall testimony, and less easily dismissed by those pedalling their tired old agenda.
And also, stop pretending that men are fast-tracked to the top. There are 13,999,908 men who aren't FTSE 100 CEOs either, as well as the 12,999,992 women this thread concentrates on (based on 92 male and 8 female FTSE CEOs in 2021). Is that the fault of the patriarchy too? All these posters claiming men never experience prejudices in the workplace should take a good look at how most men are actually employed. Clue - they aren't all partners in law firms or IT directors ordering coffee be brought to them. Many men are overlooked for promotions for a whole range of factors, some fair, some not - wrong school, wrong social background, too short, no presence, but most commonly of all ... they are simply not good enough. Which, on the balance of probabilities, is also the most likely explanation for why women get overlooked too.
