You have a right to software you can use, regardless of your disability.
There are a number of laws asserting this, as Deafgeek notes.
The Americans with Disabilities Act, The Individuals with Disabilities Education Act. The Individuals with Disabilities Education Improvement Act of 2004. The Rehabilitation Amendments -- they are all there to be used.
Trouble is they are not used often enough.
Most states have such laws as well. Even states like Texas -- just because they're "red" in the conventional political sense does not mean they're blind to your concerns. CustomerServant today covers a lawsuit being filed in Texas on behalf of blind state employees, owing to the fact that Oracle software does not support screen readers.
It was the National Federation for the Blind which filed the suit.
But why are we waiting for organized activists? As a disabled person who has the capacity to work and a desire to work, you have a right to private action. Let your employer know this, and if they give you guff, retain a lawyer.
