Mental impairment. How does the employer know? Cox v Essex County Fire and Rescue Service – 13 KBW Employment
“When facing a reasonable adjustments claim one of the first lines of defence for an employer is knowledge. An employer can avail itself of the defence of lack of knowledge of the disability (s.20 of Sch 8 of the Equality Act 2010) if it did not know, and could not reasonably have been expected to know, that the person had a disability. The defence is an impenetrable shield and often forms a key battleground at trial.”
