Stonewall said: “Our diversity champions programme and Workplace Equality Index are voluntary initiatives designed to support organisations to create more inclusive workplaces for their LGBTQ+ employees. It is hard to make a case that anyone is adversely affected by small tweaks that make HR policies more inclusive, such as for example replacing ‘mother’ or ‘father’ with ‘parent’ to ensure same-sex couples enjoy the same childcare benefits as straight couples.”
