Workforce Equality, Equity, Diversity and Inclusion Statement We are dedicated to creating an inclusive and equitable workforce, where everyone is treated with dignity and respect. Our workforce strategy places equality, equity, diversity, and inclusion at the heart of everything we do, reaffirming our commitment to fostering a culture of inclusion. We strive to create an environment where all colleagues feel they belong and can safely express their thoughts, ideas, and challenges, without fear of judgement or discrimination. We maintain a zero-tolerance approach to any unlawful discrimination, harassment, or victimisation on the grounds of any protected characteristics under the 2010 Equality Act, including but not limited to race, disability, sexual orientation, sex, religion and belief, age, gender reassignment, marriage and civil partnership, pregnancy, and maternity. Any incidents of discrimination will be promptly investigated and addressed in line with our HR policies to ensure a safe and inclusive environment for all colleagues. We use data to identify and address disparities, ensuring that our policies and practices are transparent and impactful in promoting a diverse representation of backgrounds and perspectives at all levels of the organisation. We look at inequality through an intersectional lens, recognising that different aspects of someone's identity can combine to create unique experiences of discrimination and disadvantage. We know that advancing diversity and inclusion is a continuous journey, and we must listen to our colleagues and learn where we can further improve. We work closely with our Colleague Forums and Trade Unions, supported by active allies from our Corporate Management Team, to monitor and evaluate our practices, identify barriers, and empower colleagues to promote equality and inclusion in the workplace.
