This page is about your work history, where you worked, what kind of work you did, how long you worked at each job, and how much you were paid.

The official SSA website says this about the work history questions;

We need to find out about your past work to decide if you can still do it. To make this decision, we need to know how you did your job. We also need to know if you learned skills on your job.

We need this information to see if there are other jobs that you have done other than your usual work. If you cannot do your usual work, we will decide if you can do another job that you did in the last 15 years. Remember that you are not disabled according to our rules unless your illnesses, injuries, or conditions prevent you from doing any job. Because people lose job skills if they do not use them for a long time, we do not consider them and you do not need to include jobs you did more than 15 years before you became disabled. If you need more room to list your jobs, use the space in Section 9 – Remarks

Social Security is supposed to decide first if you can perform the duties of your last job, and second, if you can do any other job that is available in the community. So they need to know what kind of work you have been doing for the last 15 years. Page 3 of the 3368 asks you to list your jobs for the last 15 years, and give additional details for the job you had the longest.

The thing is, after you fill out a 3368 and submit it for your claim, later on you will get a more detailed questionnaire in the mail about your work history. It’s the Work History Report form 3369. Most people struggle to complete page 3 of the 3368, and then think they are done with that part of their claim, only to find out later on they have to fill out a 3369 form, asking more questions. And many of those people forget what they put on the 3368!

So, do yourself a favor, just go get a Work History Report Form 3369, and fill that out.
