What an excellent piece. Calm, clear, unequivocal.
Almost whooped when I got to this:
Clearly, organisations should be trans inclusive and non-discriminatory. This does not however, mean that forces must replace single-sex facilities and policies (as based on physical sex) with those based on self-defined gender identity.
There may also be a risk of indirect discrimination if facilities that involve undressing are not provided in a way that allows female officers and staff to have privacy from males (and vice versa).
In practice, balancing rights within the workplace may mean providing additional unisex or single occupancy facilities for transitioning or non-binary staff, while retaining single-sex facilities.
The Equality Act 2010 allows organisations to provide single-sex services if it is a proportionate means of achieving a legitimate aim, such as privacy and safety. A person with the characteristic of gender reassignment might be excluded from the facilities of the sex they identify with, even where they have changed their legal sex by means of a Gender Recognition Certificate, again where it is a proportionate means of serving a legitimate aim.
