The OECD has published a policy brief discussing the measures countries have taken to support the livelihoods of those who cannot access unemployment benefits or short-term work schemes.

"These measures have helped to sustain the incomes of many and minimise initial job losses. But they have not reached all those whose livelihoods are affected. Even in countries with the most advanced systems of social protection, some workers and their families miss out: workers with non-standard jobs – the self-employed, temporary, and informal workers, and those who work very short hours – are often not covered by insurance-based  unemployment and sickness benefit schemes. Others, who were already out of work before the crisis, now face protracted hardship. The situation is worse in countries with large informal sectors and weak social protection systems where growing numbers of people lose work without any access to income support."
