The Social Security Administration defines "light" work as sitting up to 2 hours in and 8 hour day, standing 6 hours in an 8 hour day and lifting 20 pounds occasionally and 10 pounds frequently. Claimants limited from performing heavy or medium work may be relegated to light work. Common jobs defined as "light" can include: security guard, cashier and stocker. Light work will require the claimant to walk or stand for a large majority of the work day. Many unskilled light jobs will require a claimant to be able to stand for long periods and require extensive use of their arms and hands to hold, grab or turn objects.
