At a meeting debating student trips, my colleagues discussed a trip to the Bank of England. The most senior woman present intervened, to comment that the trip organiser would need to supervise the female students in the group especially closely, as they would otherwise attempt to turn it into a shopping trip. All staff shift uncomfortably in their seats. No one commented. I suspect they would have done if this comment had been made by a man.
How best to challenge routine sexism, particularly when this is perpetuated by women?
