Glass ceiling
"because of the effects of his dyslexia, he would in practice face a glass ceiling..."
If a person has a disability such as Dyslexia why should they be given extra time for an exam designed to pick up how well they would perform the tasks in their new job?
I'm a fan of the laws when they protect discrimination, such as not hiring someone in a wheel chair to answer the phone when being in the wheel chair does not affect the job, that’s a positive step.
I don't however see how giving a dyslexic longer in a test is any advantage if reading and writing are going to be part of their future job, shouldn't they have to perform these well to qualify?
For a qualification such as a degree where the knowledge of the subject is being examined then extra time is again a positive step, as the material is examined.
But if you sit two people down for an job interview for a job which requires reading and writing skills, giving a dyslexic extra time to perform the same task is a bias towards them which seems to serve no purpose, and if the extra time gives that applicant a better score and his job performance is worse (it is quite possible the dyslexia won't affect his/her performance that much, but then why would they need extra time in that case) then the employer is forced to hire the worse candidate.
The use of the anti discrimination laws should be done with the context in mind.
