The disability discrimination provisions of the Equality Act 2010 prohibit employers from treating workers less favourably than others on account of their disability. Disabled workers are also protected from being required to meet criteria which they cannot achieve, or which they would find much harder to meet than a non-disabled person, unless the criteria are objectively justified.
Employers also have a duty to take steps and make 'reasonable adjustments' to prevent a disabled person from being at a substantial disadvantage at work. And in common with all protected groups, disabled people are protected from suffering harassment and/or victimisation (i.e. retaliation for having raised or supported a complaint of discrimination).
