My sister is physically disabled and works a clerical job part-time. She continually has to watch her hours at her job because if she makes too much money, she is required to pay back the difference in her SSI disability cheque. Please note that her combined income from work and disability benefits is peanuts - it's enough to live on in a rural Midwestern town where things haven't gone up shit creek as badly as the Rust Belt and Appalachia, but it's no glamourous lifestyle and the requirement to stay underneath certain income lest you lose your SSI benefits is a perverse incentive not to try and find better work.
