I was reading a web development book last night that rehashed the widely-believed fiction that an inaccessible web page is excusable because it’s only for internal use.
Saying accessibility doesn’t matter on internal-facing pages or intranets is simply a way of saying that your company has a discriminatory recruitment policy. You’re saying that your company doesn’t and won’t have disabled workers.
I am not a lawyer, but I know some. In the UK, employers have a duty under sections 4, 5 and 6 of the Disability Discrimination Act not to treat their employees badly because of their disability.
Other nations with civilised anti-discrimination legislation have similar laws.
Last year, the average tribunal award for disability discrimination in the UK was £52,087, compared with an average of £18,584 for race discriminaion, and £19,499 for sex discrimination (source: Daily Telegraph).
