There are 9 staff, not including a few advisors. So its probably the case that they all knew each other before the comapny existed. If there were no women in their lab, theres not much they can do about that.
What would the correct response be? "Sorry we didn't know any women when we started, we shouldnt have done anything until the right quota of women showed up."
Should they fire and replace 4 staff with women or just hire 9 women even though they might not have enough revenue to do so?
