There is no truth in the view that people with disability generally have a poor work ethic. Many are actually more dedicated as securing the job in the first place may not have been easy and they are glad to be working.
Most people with disability have the same levels of work motivation as their co-workers and others. Indeed people in receipt of the Disability Support Pension are not required to look for work; their workforce participation is entirely voluntary and they are usually very motivated to find and keep a job.
You can also stress to employers that your employment service screens job candidates not only for skills, but for motivation prior to active job search and those with disability related motivation issues can receive pre-employment counselling and additional vocational assistance.
Research has found a strong general business case to support the employment of people with disability with over 90 per cent of surveyed employers who had recently hired such workers stating they would be happy to continue employing them in the future (Graffam et al 2002).
