Something for those who are disabled and collect Social Security Disability (aka green check) or Social Security Income (gold check) and is pretty much mostly young and pre-retirement-age disabled folks: if your income goes over half of what you take in from Social Security, your eligibility will be "threaten" and re-evaluation WILL occur, often with reducing benefits until you earn twice what SSA gives you.
So, if the job doesn't pan out, you are going to be in a rather severe financial bind for quite a awhile until those re-applied benefit(s) restarts for you.
Hence, many disabled are looking for work that do not pay more than $800-1200/month (USD) ... just to avoid their re-evaluation trigger.
