69.This section provides that it is discrimination to treat a disabled person unfavourably not because of the person’s disability itself but because of something arising from, or in consequence of, his or her disability, such as the need to take a period of disability-related absence. It is, however, possible to justify such treatment if it can be shown to be a proportionate means of achieving a legitimate aim. For this type of discrimination to occur, the employer or other person must know, or reasonably be expected to know, that the disabled person has a disability.
