Bring defined as "disabled" doesn't mean they can't work. Of course, "some" disabilities mean employment is simply not an option, but the majority of "disabled" people DO work. We need to provide better advice/support to get disabled people into the workplace, that's support for BOTH the person themselves and employers.
I was once sat on a plane on the tarmac at an airport and watched a one legged baggage handler load the suitcases! That was incredibly impressive and showed what people can do if they want to.
I remember when I started work in the 80s, in the first 2/3 firms I worked at, we had a number of staff who'd today be classed as Autistic, or on the spectrum, or Aspergers, etc., due to their mannerisms, but back then, they were just regarded as shy or a bit withdrawn, but they were still able to do their jobs in the workplace. Likewise back a bit further in school, one lad in our class, looking back, clearly was autistic, but we all just thought he was a bit weird as he never joined in, never talked to other pupils, just sat at his desk and worked. Looking back now that there's more awareness and knowledge, he was clearly "disabled" under modern ways of thinking.
