States must ensure that social protection systems do not create significant inequalities between those who have an interrupted participation in the labour force - due for example to parenthood, care for older persons or persons with disabilities - and those who do not. At a minimum, States must provide universal non-contributory social pensions that are sufficient for an adequate standard of living, and ensure that women living in poverty can access them. The introduction of carer credits into a country's pension or superannuation system can provide a method of explicitly recognizing those years spent providing unpaid care.
