"The respondent subjected the claimant to a detriment in issuing her with a final written warning on15 December 2016 which was unfavourable treatment because of something, her refusal to comply with a management instruction, which arose in consequence of her disability of osteoarthritis…."
"20. …. firstly, to provide a wind chill temperature thermometer to display the adjusted ambient temperatures; secondly, to provide a local windbreak between the workstation closest to the bay doors; thirdly, to adjust the height of the printer in her primary pod; fourthly, to provide her with thermal underclothing; and fifthly, to provide the claimant with a localised heating resource, but he said that a fan heater might cause problems with other colleagues or pose a fire risk."
"22. Over a period from24 January 2017 to3 June 2017 temperature measurements were taken every hour between 10a.m. and 9 p.m., at three of the workstations. Over the period they demonstrate a variance between 16 degrees and 20 degrees. The difference in temperature between the end and the near benches was, at most, half a degree and there was no visible change with regard to chill factor. Peculiarly, the chill factor measurements hardly differed from the normal temperature measures, and in certain instances, when they did, they showed a higher temperature than the normal temperature. To a lay person that would not appear to be likely, as one would expect, in cold weather; wind chill to reduce the temperature level. We had no informed opinion to assist on whether this undermined the accuracy of the readings. Be that as it may, there is no significant difference in the readings from one part of the building to the other. What is noticeable, is that from one day to another there is a significant change in temperature in the warehouse as a whole, up by four degrees..."
"33. We find that the issuance of the final written warning was unfavourable treatment. We find it was because the claimant refused to comply with instruction to work on the end benches on 6 and9 December 2016 . We find it arose in consequence of the claimant's disability. The claimant refused to work on the end benches on those dates because she believed that it would adversely affect her health. She believed that, because her doctor had confirmed that colder temperatures impacted upon her symptoms and, as that part of the workplace was closer to the outdoors, she feared that she would suffer greater discomfort and pain. …. 36. It is not disputed that the warning was issued because of the refusal to comply with the management instruction; a refusal which the managers contended was an unreasonable one. Did the refusal arise in consequence of the disability? The claimant did not refuse for any other reason than she believed compliance would adversely impact upon her health: that is a condition of osteoarthritis, which was and is a disability. The essential components of Section 15(1)(a) of the EqA are established."
"37. …at the time of her refusal to comply with the instruction, the claimant held a genuine belief that she would have been adversely affected working closer to the doors, and that it was a reasonable belief at that time. That is because the claimant did not have extensive temperature readings, but knowing she was vulnerable to cold weather and seeing the benches furthest from the wall but nearer to the doors she thought that it would be colder in that part of the premises. She had worked in the premises for many years and would have formed a view about which parts were colder.... We are satisfied from the evidence, taken as a whole, that the claimant's belief that working at end benches was a cooler environment than the furthest benches was a reasonable one. For reasons we developed later we find that that was a mistaken belief."
"38. If it had been suggested, for example, that a legitimate aim to the provision of the warning was to ensure the work was done most efficiently and fairly distributed, it would not have been a proportionate means to achieve that aim to discipline a disabled person for refusing to comply with an instruction when the disabled person reasonably believed their health would be adversely affected if the instruction were not complied with…"
"15. Discrimination arising from disability (1) A person (A) discriminates against a disabled person (B) if— (a) A treats B unfavourably because of something arising in consequence of B's disability, and (b) A cannot show that the treatment is a proportionate means of achieving a legitimate aim. (2) Subsection (1) does not apply if A shows that A did not know, and could not reasonably have been expected to know, that B had the disability."
"36. On its proper construction, section 15(1)(a) requires an investigation of two distinct causative issues: (i) did A treat B unfavourably because of an (identified) "something"? and (ii) did that "something" arise in consequence of B's disability. 37. The first issue involves an examination of A's state of mind, to establish whether the unfavourable treatment which is in issue occurred by reason of A's attitude to the relevant "something" ... 38. The second issue is an objective matter, whether there is a causal link between B's disability and the relevant "something" …."
"39. In my view… it is not possible to spell out a section 15(1)(a) a further requirement, that A must be shown to have been aware when choosing to subject B to the unfavourable treatment in question that the relevant "something" arose in consequence of B's disability (i.e. that A should himself be aware of the objective causation referred to issue (ii) above….."
