Did the manager have a bias against women because they feel women are worse workers? What caused that bias and how can it be fixed (sadly, in some cases it can only be fixed in the younger generations... or maybe this is a bias I have against older individuals... and why would I have that).
Did the manager have a bias against women because a previous project was massively delayed when a woman took maternity leave and the temp replacement took so much onboarding work that they might have been better being a person down? How about changing culture so a later delivery cue to someone taking medical leave is 100% as acceptable as an earlier delivery (including the same end of year bonuses).
Did the manager have a bias against women because some of their male employees fear an instance similar to Donglegate and as such would be far less open to forming the same sort of comradeship that enables the team to run smoothly? What caused the employees to feel this way?
Did the manager have a bias against women because they are male and they fear for their own professional safety when conducting private one on one meetings with the opposite set? Why do they fear such and can that fear be removed.
Do you have any data, which controls for the appropriate variables, to support that?
It's shooting in the dark.
I take that to mean you don't have those facts? Because it would be easier and more trustworthy to simply put them on the table than berate the gp for posting a reasonable question.
That's what is being done right here, right now.
I find that pretty much every woman in the tech industry who I've spoken to has at least one example of how they feel they've been discriminated against at some point.
Then sharing some concrete examples should be easy!
As soon as people stop using it as an excuse to abuse, berate, degrade and discriminate against people. These words, and the intent behind them, are not the problem - they are a reaction to the problem. Rather than get annoyed with people who invent words like 'wogrammers', why not direct your anger toward the employers who refuse to hire women, or pay them less, or ignore sexual harassment. Those people are the problem.
