Be yourself, be natural, don't force enthusiasm. Do not patronise or be inappropriately solicitous. A disability is not necessarily an illness. Do not treat people with disabilities as though they are sick. Treat them as healthy individuals.
Research indicates that people with disabilities take fewer sick days than other employees.
Their impairments cause inconvenience and disability in particular areas of activity, but they are rarely dysfunctional. Treat people in a manner that is appropriate to their age. It is not appropriate to talk to people with disabilities as if they were children, nor to refer to them as children. Speak directly to the person, not to their carer or other third party. People with disabilities often have carers.
