The duty to make reasonable adjustments applies if the employer knows (or ought to know) that the employee has a disability and is disadvantaged by the employer's arrangements. Wilcox v Birmingham CAB Services in the EAT suggests that a general awareness of problems is not sufficient to assume knowledge. The claimant, who suffered from agoraphobia and travel anxiety, resigned when her employer refused to move her (on a guaranteed permanent basis) to an office closer to her home. Her claim for failure to make reasonable adjustments was rejected because although her managers were aware of her travel anxiety, they had no actual or constructive knowledge of her disability as required by the statute until the point when they should reasonably have obtained authoritative medical advice.
