My answer is obvious, but I'll leave it here to start with.
We need to reduce the representation of women in education massively. The majority of women seeking these roles have malicious intent, and are actively harming young boys.
We know they don't mark boys fairly, but that's just the peak of the insidious feminist plot.
They've clearly been destroying the self-worth of boys in the schools to groom a new generation of woman worshipping simps.
Unions are necessary because administrators have proven themselves to be retaliatory against good teachers. They can actually help retain a good teacher who the admins would rather leave as that person disrupts their narrative.
