“Text is not a feature of Websites; it is a primitive, a fundamental and unalterable component” - Joe Clark
Why accessibility? • The business case • The ethical case • The legal case
The business case “The estimated spending power of people with disabilities in the UK being £40-50 billion” Employers Forum on Disability
The ethical case • The social model of disability • Cooperate social responsibility
The legal case • “...we are now using the force of argument. If that fails, we will not hesitate to use the argument of force.” • -- Bert Massie Chairman, Disability Rights Commission
Intranets “One major UK corporation which is notorious for having inaccessible public web pages, is suddenly spending considerable sums on making their intranet accessible - for no other reason (as far as my informant could tell) than because they'd realised they risked some rather high-profile court actions by employees.” -- Alan Flavell. (Alan Flavell is a well-known contributor to html-related newsgroups – he has a lot of respect within the industry. He is an acknowledged expert. His credentials are impeccable)
Intranets “A member of staff could (we hope not, but it happens) lose their sight (or 'gain' some other disability) at any time. Equally, you could employ someone. If this happens down the road, you could have a massive problem.” -- Anonymous Contributor (Intranet Forum)
