People should be able to use toilet and changing facilities appropriate to their gender identity.
Providing gender neutral toilet and changing facilities is supportive of trans people, including those who are non-binary. It avoids potential problems that may arise if there is a discrepancy between physical appearance and inner sense of gender. It provides a private space, where the right to use the facilities will not be challenged. There may be times when trans members of staff feel unable to express their gender identity in public, or when travelling to and from work, for fear of transphobic attack. However they may want somewhere to change so that they can freely express their gender identity at work.
