Lesbian, gay, bisexual and trans (LGBT) diversity includes all aspects of sexuality and gender identity. Employees perform best when they can be themselves so its important that employers provide a framework to ensure people identifying as LGBT are fully included. LGBT is sometimes lengthened to include Q (queer) and I (intersex) to make LGBTQI or LGBT+.
Homosexuality was decriminalised in the UK in 1967 but a ban continued in the armed forces until an ECHR ruling in 2000.
