Really excellent questions!
It's hard for me to use my own personal experience in this particular role, as I already work in an industry that is overrun by white older men.
Do you think that pay offers for white men tend to be higher than those for people of colour and women?
In many industries, yes. In our own company, no and we have undertaken data analysis yearly to keep on top of this.
How do you ensure that unconscious bias doesn't impact the assessment of how much people are worth?
When candidates ask for a higher salary, the request has to be signed off by SMT with no personal details given e.g name. The decision is based on merit alone based on their experience.
Do you do anything to counter the fact that women (especially black women) are conditioned to ask for less to avoid appearing pushy it aggressive?
No - and this is a really good point that I am going to bring up - thank you.
