Light work is one of the five job classifications used to designate maximum sustained work capacity. The SSA will determine your maximum sustained work capability by reviewing your medical records and other evidence, including the questionnaires completed during the claims process. The SSA is very thorough during the review process and it is important to be detailed about all of your conditions and limitations during the application process. If the SSA determines you are able to perform light work, your disability application may not be approved, taking into consideration your age, education, training, and work experience. Light work is defined as being able to lift up to 20 pounds at a time, as well as being able to frequently lift up to ten pounds per 8-hour shift. To be able to perform light work you must be able to stand for up to 6 hours per 8-hour shift. However, if you are unable to perform any aspect of light work you will not be eligible for any of it.
