In any kind of management role you should have good general knowledge of issues which may affect your line of work. This includes an awareness of the news etc. I've literally been on management courses telling me this.

She doesn't know about Stonewall.
She doesn't know about the Equality Act.
This woman is so far out of her depth it HURTS.
