Social Security defines the word “disability” in terms of how your medical problems prevent you from working. Therefore, if you are able to work, you are not disabled under this definition and most of the time SSA will not even take an application from you,
If you are working part time, SSA may or may not take a disability application - so as a rule you want to be able to say that you are not working when you apply for disability.
As I have discussed in another video - https://youtu.be/qrJ_cBKWZHM - on-going, part-time work will make it more difficult for you to win disability benefits. Unfortunately, given the long delays - sometimes 3 years from application date to disability hearing - you may have no choice but to try to work so that you will have the money for food and shelter.
If you do decide to try to work while your disability application is pending, make sure to discuss with your attorney the differences between an unsuccessful work attempt and a successful return to work that counts as substantial gainful activity.
