Sometimes a prior job is actually more than one job at the same time. You were both a RN and a nurse supervisor. You were both a receptionist and a filing clerk. You were both a carpenter and a construction supervisor. These are called composite jobs.
If your past relevant work included a composite job, it can cause problems with your Social Security disability claim. The SSA must determine, at step 4 of the 5-step sequential evaluation process, whether you have the residual functional capacity to perform your past relevant work. Not only does Social Security consider your ability to do your past work as you performed it, but also as generally performed. And this is where the composite job can cause problems with a claim.
Typically, in the short space available on the work history report, you only give the job title for part of your composite job. Then you describe what you had to do. Social Security may find that you can’t do the job as you describe it, buy can still do that job as generally performed. The problem is that the “generally performed” analysis does not consider the composite nature of the job. The SSA will just use the job title that you gave in your work history report to determine how the job is generally performed in the Dictionary of Occupational Titles (DOT). If that past job was a composite job, this approach is incorrect under Social Security’s own rules.
