One of the changes I know is that indirect discrimination would be recognised now. It just means that an employer should not introduce a criteria, practice or provision that would put disabled people at an disadvantage.
Well, for one you really couldn't make typing speed as one of the criteria in a performance review. This is because most dyslexics cannot type fast, and as such you are indirectly discriminating against people who suffer from dyslexia.
Another thing that employers should watch out for is the fact that they could now be punished for the consequences of a person's disability. For example, you could not fire out an employee who has been absent due to treatments for his disability.
Not only that... the new law says that you don't have to compare yourself with another employee without the disability, which is what the current law requires.
