This site has been sent to me by my child's secondary school:
www.equalityhumanrights.com/en/equality-act/protected-characteristics
and it says that the 9 protected characteristics under the Equality Act 2010 are:
age
disability
gender reassignment
marriage and civil partnership
pregnancy and maternity
race
religion or belief
sex
sexual orientation
Is gender eassignment a protected characteristic? I didn't think it was?
