The question an employer needs to ask themselves is whether:

• the way they do things
• any physical feature of their workplace
• the absence of an auxiliary aid or service

puts you, as a disabled worker or job applicant, at a substantial disadvantage compared with a person who is not disabled.
Anything that is more than minor or trivial is a substantial disadvantage.

If a substantial disadvantage does exist, then the employer must make reasonable adjustments.

The aim of the adjustments the employer makes is to remove or reduce the substantial disadvantage.

But the employer only has to make adjustments that are reasonable for them to make. There is more information about how to work out what is reasonable a bit later in this part of the guide.
