Striving for a better gender balance

For gender equality, there can be no glass ceiling. At Allen & Overy we are determined to achieve a better gender balance at all levels of our organisation, and are working hard to make sure that all of our people have the same opportunities to realise their ambitions.

Race and ethnicity - enabling diverse people to thrive

The world is full of different. Are we truly a global firm if our business is not? We’re striving to attract talented, racially and ethnically diverse people, and create an environment where our colleagues not only feel that they belong – they feel they can thrive.

Supporting our LGBTQ+ colleagues and communities

Supporting our colleagues with disabilities

Sometimes what makes us different is visible. Sometimes it isn’t immediately obvious. We know that differences can be life-changing and can change over time.
