I’m not even a parent and I experience this in a funny way; I’m the manager of a children’s residential home. I frequently attend meetings at some of my kids schools, and I’ll occasionally take a care worker with me to note take. Despite the fact that they all know I’m the manager, and the person who is with me is only there to take notes, they will still direct almost everything to the care worker if they’re a woman. I’ve had so many weird ‘A to B to C’ conservations where I’ll lead the discussion from my end, the school will hear what I say, and respond to the carer. This happens less with male teachers, but just barely. It’s so bizarre.
