It is illegal and immoral to discriminate on account of disability.
It is in fact not illegal nor immoral to discriminate on account of a disability. It is only so if the discrimination is unjust.
If the disability means they cannot perform the job to normal expectations then they do not have to be given it and it may be immoral (which has a subjective test) to give it to them.
The examples are endless to come up with even for a lazy mind. But simply a one armed paperhanger may get the job but a no armed one won't.
In the case of a totally deaf person I would be most surprised if a business would be accused of unjust discrimination if they decided to not employ a person where it was essential for the job that they could hear and it would be considered by many immoral for them to do so if hearing was essential for the worker's safety. And the employer would not be expected to employ another person nor to buy special technology assistance just to assist such a person to do the job that another otherwise could.
So I have some unease as to how she got the job she now has. That said I have in the past wondered who pays for Stephen Hawking's voice synthsiser and technician?
I love watching you work :)
