________
A person can be engaging in SGA even if the work is *part-time*. The
primary consideration for an employee who is actually working is the
amt. of non-subsidized earnings minus allowable expenses.
But if a person is not working and it's necessary to evaluate the
medical and vocational evidence to determine if (s)he's capable of
perfoming SGA, they consider his/her ability to perform SGA on a
*full-time* basis. This means 8 hrs. a day X 5 days a week.
