"The claimant's claim that the respondent failed to make a reasonable adjustment undersection 4A of the Disability Discrimination Act 1995 when it gave him a twelve month written warning (running from1 April 2008 ) for leaving work without permission succeeds."
"6. … Miss ED commenced disciplinary proceedings against the claimant for leaving without permission. She concluded (on the basis of advice that she received from Human Resources) that this was minor misconduct of a more serious nature and merited a twelve month written warning. This decision was upheld following an appeal … 7. The claimant had explained to both ED and JW that his actions had been affected by his medical condition and that he had, by then, been prescribed anti-depressants by his GP. No medical investigation took place at that stage (i.e. during the disciplinary proceedings) and prior to the disciplinary sanction being awarded."
"(1) Where – (a) a provision, criterion or practice applied by or on behalf of an employer, or (b) any physical feature of premises occupied by the employer, places the disabled person concerned at a substantial disadvantage in comparison with persons who are not disabled , it is the duty of the employer to take such steps as it is reasonable , in all the circumstances of the case, for him to have to take in order to prevent the provision , criterion or practice , or feature , having that effect."
"(3) Nothing in this section imposes any duty on an employer in relation to a disabled person if the employer does not know, and could not be reasonably expected to know – … (b) in any case, that that person has a disability and is likely to be affected in the way mentioned in subsection (1)."
"11. In our view, subsection (3)(b) means that an employer is exempt from the duty to make adjustments if each of four matters can be satisfied and they are that the employer: i. does not know that the disabled person has a disability; ii. does not know that the disabled person is likely to be at a substantial disadvantage compared with persons who are not disabled; iii. could not reasonably be expected to know that the disabled person had a disability; and iv. could not reasonably be expected to know that the disabled person is likely to be placed at a substantial disadvantage in comparison with persons who are not disabled. 12. It is necessary to stress that these are cumulative and not alternative requirements and that is because of the use of the word 'and' in two significant places in subsection (3), which is set out in paragraph 5 above. The first use of the word 'and' is between the words; 'the employer does not know' and the words 'could not reasonably be expected to know'. The second is between the words 'the person has a disability' and 'is likely to be affected in the way…' 13. If the draftsman of this provision had intended the requirements to be alternative rather than cumulative, surely he or she would have used the word 'or' rather than the word 'and'. Indeed, what is clear is that the section cannot be construed so that 'and' means 'or'."
