Social Security disability benefits can be ceased if, during a Continuing Disability Review (CDR), the medical evidence shows that you have significant medical improvement and are able to return to work OR you do return to work, use your trial work period and extended period of eligibility and demonstrate that you are able to engage in substantial gainful activity.

All very complex. Very few people, once entitled, ever go off of disability benefits. The agency is behind on CDR processing so there are probably many many people who could work who still get money every month.

There is no termination for simply refusing to take a job.
