Systemic racism
Sometimes groups and organisations can have rules that seem to be fair to everyone – but they actually make things more difficult for people from particular cultural or ethnic backgrounds.
This is also known as structural or systemic racism.
For example, a bank might ask everyone to fill out a lot of forms in English before you can open an account. That makes it hard for people who don't speak English as their first language.
It might also happen when an employer has a policy of not hiring people who have been educated at an overseas school or university.
