Let me just clarify what I meant. If you have a filter for male and female staff, you are signaling out one sex over the other. For example, I want a female so and so or a male so and so. There are female staff in the game, but I don't go through the list of staff and choose who I want based on sex. I chose the ones with the best attributes.
IRL you can't filter candidates between sex so adding it to the game would cause a lot of kick back, I think. It would be like adding a filter based on skin colour which would be unacceptable.
