Social security is linked in many ways to employment status. Those in paid employment are better covered, often, than those whose work goes unpaid. Moreover, many social insurance schemes base their financing model on employment-related contributions. Gainful employment includes productive work performed by employees or by the self-employed. Yet, not all work counts as gainful employment. Unpaid work such as housework, helping out neighbors, or volunteering – work predominantly performed by women – is excluded.
